Finally Getting the Most out of the Java Thread Pool | @CloudExpo #JVM #Java #Cloud
Thread pool is a core concept in multithreaded programming that represents a collection of idle threads used to execute tasks

Finally Getting the Most out of the Java Thread Pool
By Eugen Paraschiv

First, let's outline a frame of reference for multithreading and why we may need to use a thread pool.

A thread is an execution context that can run a set of instructions within a process - aka a running program. Multithreaded programming refers to using threads to execute multiple tasks concurrently. Of course, this paradigm is well supported on the JVM.

Although this brings several advantages, primarily regarding the performance of a program, multithreaded programming can also have disadvantages - such as increased complexity of the code, concurrency issues, unexpected results and adding the overhead of thread creation.

In this article, we're going to take a closer look at how the latter issue can be mitigated by using thread pools in Java.

Why Use a Thread Pool?
Creating and starting a thread can be an expensive process. By repeating this process every time we need to execute a task, we're incurring a significant performance cost - which is exactly what we were attempting to improve by using threads.

For a better understanding of the cost of creating and starting a thread, let's see what the JVM actually does behind the scenes:

  • It allocates memory for a thread stack that holds a frame for every thread method invocation
  • Each frame consists of a local variable array, return value, operand stack and constant pool
  • Some JVMs that support native methods also allocate a native stack
  • Each thread gets a program counter that tells it what the current instruction executed by the processor is
  • The system creates a native thread corresponding to the Java thread
  • Descriptors relating to the thread are added to the JVM internal data structures
  • The threads share the heap and method area

Of course, the details of all this will depend on the JMV and the operating system.

In addition, more threads mean more work for the system scheduler to decide which thread gets access to resources next.

A thread pool helps mitigate the issue of performance by reducing the number of threads needed and managing their lifecycle.
Essentially, threads are kept in the thread pool until they're needed, after which they execute the task and return the pool to be reused later. This mechanism is especially helpful in systems that execute a large number of small tasks.

Java Thread Pools
Java provides its own implementations of the thread pool pattern, through objects called executors. These can be used through executor interfaces or directly through thread pool implementations - which does allow for finer-grained control.

The java.util.concurrent package contains the following interfaces:

  • Executor - a simple interface for executing tasks
  • ExecutorService - a more complex interface which contains additional methods for managing the tasks and the executor itself
  • ScheduledExecutorService - extends ExecutorService with methods for scheduling the execution of a task

Alongside these interfaces, the package also provides the Executors helper class for obtaining executor instances, as well as implementations for these interfaces.

Generally, a Java thread pool is composed of:

  • The pool of worker threads, responsible for managing the threads
  • A thread factory that is responsible for creating new threads
  • A queue of tasks waiting to be executed

In the following sections, let's see how the Java classes and interfaces that provide support for thread pools work in more detail.

The Executors class and Executor interface
The Executors class contains factory methods for creating different types of thread pools, while Executor is the simplest thread pool interface, with a single execute() method.

Let's use these two classes in conjunction with an example that creates a single-thread pool, then uses it to execute a simple statement:

Executor executor = Executors.newSingleThreadExecutor();
executor.execute(() -> System.out.println("Single thread pool test"));

Notice how the statement can be written as a lambda expression - which is inferred to be of Runnable type.

The execute() method runs the statement if a worker thread is available, or places the Runnable task in a queue to wait for a thread to become available.

Basically, the executor replaces the explicit creation and management of a thread.

The factory methods in the Executors class can create several types of thread pools:

  • newSingleThreadExecutor() - a thread pool with only one thread with an unbounded queue, which only executes one task at a time
  • newFixedThreadPool() - a thread pool with a fixed number of threads which share an unbounded queue; if all threads are active when a new task is submitted, they will wait in queue until a thread becomes available
  • newCachedThreadPool() - a thread pool that creates new threads as they are needed
  • newWorkStealingThreadPool() - a thread pool based on a "work-stealing" algorithm which will be detailed more in a later section

Next, let's take a look into what additional capabilities the ExecutorService interface.

The ExecutorService
One way to create an ExecutorService is to use the factory methods from the Executors class:

ExecutorService executor = Executors.newFixedThreadPool(10);

Besides the execute() method, this interface also defines a similar submit() method that can return a Future object:

Callable<Double> callableTask = () -> {
return employeeService.calculateBonus(employee);
};
Future<Double> future = executor.submit(callableTask);
// execute other operations
try {
if (future.isDone()) {
double result = future.get();
}
} catch (InterruptedException | ExecutionException e) {
e.printStackTrace();
}

As you can see in the example above, the Future interface can return the result of a task for Callable objects, and can also show the status of a task execution.

The ExecutorService is not automatically destroyed when there are no tasks waiting to be executed, so to shut it down explicitly, you can use the shutdown() or shutdownNow() APIs:

executor.shutdown();

The ScheduledExecutorService
This is a subinterface of ExecutorService - which adds methods for scheduling tasks:

ScheduledExecutorService executor = Executors.newScheduledThreadPool(10);

The schedule() method specifies a task to be executed, a delay value and a TimeUnit for the value:

Future<Double> future = executor.schedule(callableTask, 2, TimeUnit.MILLISECONDS);

Furthermore, the interface defines two additional methods:

executor.scheduleAtFixedRate(
() -> System.out.println("Fixed Rate Scheduled"), 2, 2000, TimeUnit.MILLISECONDS);

executor.scheduleWithFixedDelay(
() -> System.out.println("Fixed Delay Scheduled"), 2, 2000, TimeUnit.MILLISECONDS);

The scheduleAtFixedRate() method executes the task after 2 ms delay, then repeats it at every 2 seconds. Similarly, the scheduleWithFixedDelay() method starts the first execution after 2 ms, then repeats the task 2 seconds after the previous execution ends.

In the following sections, let's also go through two implementations of the ExecutorService interface: ThreadPoolExecutor and ForkJoinPool.

The ThreadPoolExecutor
This thread pool implementation adds the ability to configure parameters
, as well as extensibility hooks. The most convenient way to create a ThreadPoolExecutor object is by using the Executors factory methods:

ThreadPoolExecutor executor = (ThreadPoolExecutor) Executors.newFixedThreadPool(10);

In this manner, the thread pool is preconfigured for the most common cases. The number of threads can be controlled by setting the parameters:

  • corePoolSize and maximumPoolSize - which represent the bounds of the number of threads
  • keepAliveTime - which determines the time to keep extra threads alive

Digging a bit further, here's how these parameters are used.

If a task is submitted and fewer than corePoolSize threads are in execution, then a new thread is created. The same thing happens if there are more than corePoolSize but less than maximumPoolSize threads running, and the task queue is full. If there are more than corePoolSize threads which have been idle for longer than keepAliveTime, they will be terminated.

In the example above, the newFixedThreadPool() method creates a thread pool with corePoolSize=maximumPoolSize=10, and a keepAliveTime of 0 seconds.

If you use the newCachedThreadPool() method instead, this will create a thread pool with a maximumPoolSize of Integer.MAX_VALUE and a keepAliveTime of 60 seconds:

ThreadPoolExecutor cachedPoolExecutor
= (ThreadPoolExecutor) Executors.newCachedThreadPool();

The parameters can also be set through a constructor or through setter methods:

ThreadPoolExecutor executor = new ThreadPoolExecutor(
4, 6, 60, TimeUnit.SECONDS, new LinkedBlockingQueue<Runnable>()
);
executor.setMaximumPoolSize(8);

A subclass of ThreadPoolExecutor is the ScheduledThreadPoolExecutor class, which implements the ScheduledExecutorService interface. You can create this type of thread pool by using the newScheduledThreadPool() factory method:

ScheduledThreadPoolExecutor executor
= (ScheduledThreadPoolExecutor) Executors.newScheduledThreadPool(5);

This creates a thread pool with a corePoolSize of 5, an unbounded maximumPoolSize and a keepAliveTime of 0 seconds.

The ForkJoinPool
Another implementation of a thread pool is the ForkJoinPool class. This implements the ExecutorService interface and represents the central component of the fork/join framework introduced in Java 7.

The fork/join framework is based on a "work-stealing algorithm". In simple terms, what this means is that threads that run out of tasks can "steal" work from other busy threads.

A ForkJoinPool is well suited for cases when most tasks create other subtasks or when many small tasks are added to the pool from external clients.

The workflow for using this thread pool typically looks something like this:

  • create a ForkJoinTask subclass
  • split the tasks into subtasks according to a condition
  • invoke the tasks
  • join the results of each task
  • create an instance of the class and add it to the pool

To create a ForkJoinTask, you can choose one of its more commonly used subclasses, RecursiveAction or RecursiveTask - if you need to return a result.

Let's implement an example of a class that extends RecursiveTask and calculates the factorial of a number by splitting it into subtasks depending on a THRESHOLD value:

public class FactorialTask extends RecursiveTask<BigInteger> {
private int start = 1;
private int n;
private static final int THRESHOLD = 20;

// standard constructors

@Override
protected BigInteger compute() {
if ((n - start) >= THRESHOLD) {
return ForkJoinTask.invokeAll(createSubtasks())
.stream()
.map(ForkJoinTask::join)
.reduce(BigInteger.ONE, BigInteger::multiply);
} else {
return calculate(start, n);
}
}
}

The main method that this class needs to implement is the overridden compute() method, which joins the result of each subtask.

The actual splitting is done in the createSubtasks() method:

private Collection<FactorialTask> createSubtasks() {
List<FactorialTask> dividedTasks = new ArrayList<>();
int mid = (start + n) / 2;
dividedTasks.add(new FactorialTask(start, mid));
dividedTasks.add(new FactorialTask(mid + 1, n));
return dividedTasks;
}

Finally, the calculate() method contains the multiplication of values in a range:

private BigInteger calculate(int start, int n) {
return IntStream.rangeClosed(start, n)
.mapToObj(BigInteger::valueOf)
.reduce(BigInteger.ONE, BigInteger::multiply);
}

Next, tasks can be added to a thread pool:

ForkJoinPool pool = ForkJoinPool.commonPool();
BigInteger result = pool.invoke(new FactorialTask(100));

ThreadPoolExecutor vs. ForkJoinPool
At first look, it seems that the fork/join framework brings improved performance. However, this may not always be the case depending on the type of problem you need to solve.

When choosing a thread pool, it's important to also remember there is overhead caused by creating and managing threads and switching execution from one thread to another.

The ThreadPoolExecutor provides more control over the number of threads and the tasks that are executed by each thread. This makes it more suitable for cases when you have a smaller number of larger tasks that are executed on their own threads.

By comparison, the ForkJoinPool is based on threads "stealing" tasks from other threads. Because of this, it is best used to speed up work in cases when tasks can be broken up into smaller tasks.

To implement the work-stealing algorithm, the fork/join framework uses two types of queues:

  • A central queue for all tasks
  • A task queue for each thread

When threads run out of tasks in their own queues, they attempt to take tasks from the other queues. To make the process more efficient, the thread queue uses a deque (double ended queue) data structure, with threads being added at one end and "stolen" from the other end.

Here is a good visual representation of this process from The H Developer:

fork/join thread pool

In contrast with this model, the ThreadPoolExecutor uses only one central queue.

One last thing to remember is that the choosing a ForkJoinPool is only useful if the tasks create subtasks. Otherwise, it will function the same as a ThreadPoolExecutor, but with extra overhead.

Tracing Thread Pool Execution
Now that we have a good foundational understanding of the Java thread pool ecosystem, let's take a closer look at what happens during the execution of an application that uses a thread pool.

By adding some logging statements in the constructor of FactorialTask and the calculate() method, you can follow the invocation sequence:

13:07:33.123 [main] INFO ROOT - New FactorialTask Created
13:07:33.123 [main] INFO ROOT - New FactorialTask Created
13:07:33.123 [main] INFO ROOT - New FactorialTask Created
13:07:33.123 [main] INFO ROOT - New FactorialTask Created 13:07:33.123 [ForkJoinPool.commonPool-worker-1] INFO ROOT - New FactorialTask Created
13:07:33.123 [ForkJoinPool.commonPool-worker-1] INFO ROOT - New FactorialTask Created
13:07:33.123 [main] INFO ROOT - New FactorialTask Created
13:07:33.123 [main] INFO ROOT - New FactorialTask Created
13:07:33.123 [main] INFO ROOT - Calculate factorial from 1 to 13
13:07:33.123 [ForkJoinPool.commonPool-worker-1] INFO ROOT - New FactorialTask Created
13:07:33.123 [ForkJoinPool.commonPool-worker-2] INFO ROOT - New FactorialTask Created

13:07:33.123 [ForkJoinPool.commonPool-worker-1] INFO ROOT - Calculate factorial from 51 to 63
13:07:33.123 [ForkJoinPool.commonPool-worker-2] INFO ROOT - Calculate factorial from 76 to 88
13:07:33.123 [ForkJoinPool.commonPool-worker-3] INFO ROOT - Calculate factorial from 64 to 75
13:07:33.163 [ForkJoinPool.commonPool-worker-3] INFO ROOT - New FactorialTask Created
13:07:33.163 [main] INFO ROOT - Calculate factorial from 14 to 25
13:07:33.163 [ForkJoinPool.commonPool-worker-3] INFO ROOT - New FactorialTask Created
13:07:33.163 [ForkJoinPool.commonPool-worker-2] INFO ROOT - Calculate factorial from 89 to 100
13:07:33.163 [ForkJoinPool.commonPool-worker-3] INFO ROOT - Calculate factorial from 26 to 38
13:07:33.163 [ForkJoinPool.commonPool-worker-3] INFO ROOT - Calculate factorial from 39 to 50

Here you can see there are several tasks created, but only 3 worker threads - so these get picked up by the available threads in the pool.

Also notice how the objects themselves are actually created in the main thread, before being passed to the pool for execution.

This is actually a great way to explore and understand thread pools at runtime, with the help of a solid logging visualization tool such as Prefix.

The core aspect of logging from a thread pool is to make sure the thread name is easily identifiable in the log message; Log4J2 is a great way to do that by making good use of layouts for example.

Potential Risks of Using a Thread Pool
Although thread pools provide significant advantages, you can also encounter several problems while using one, such as:

  • Using a thread pool that is too large or too small - if the thread pool contains too many threads, this can significantly affect the performance of the application; on the other hand, a thread pool that is too small may not bring the performance gain that you would expect
  • Deadlock can happen just like in any other multi-threading situation; for example, a task may be waiting for another task to complete, with no available threads for this latter one to execute; that's why it's usually a good idea to avoid dependencies between tasks
  • Queuing a very long task - to avoid blocking a thread for too long, you can specify a maximum wait time after which the task is rejected or re-added to the queue

To mitigate these risks, you have to choose the thread pool type and parameters carefully, according to the tasks that they will handle. Stress-testing your system is also well-worth it to get some real-world data of how your thread pool behaves under load.

Conclusion
Thread pools provide a significant advantage by, simply put, separating the execution of tasks from the creation and management of threads. Additionally, when used right, they can greatly improve the performance of your application.

And, the great thing about the Java ecosystem is that you have access to some of the most mature and battle-tested implementations of thread-pools out there, if you learn to leverage them properly and take full advantage of them.

"IBM is really all in on blockchain. We take a look at sort of the history of blockchain ledger technologies. It started out with bitcoin, Ethereum, and IBM evaluated these particular blockchain technologies and found they were anonymous and permissionless and that many companies were looking for permissioned blockchain," stated René Bostic, Technical VP of the IBM Cloud Unit in North America, in this SYS-CON.tv interview at 21st Cloud Expo, held Oct 31 – Nov 2, 2017, at the Santa Clara Conventi...
Gemini is Yahoo’s native and search advertising platform. To ensure the quality of a complex distributed system that spans multiple products and components and across various desktop websites and mobile app and web experiences – both Yahoo owned and operated and third-party syndication (supply), with complex interaction with more than a billion users and numerous advertisers globally (demand) – it becomes imperative to automate a set of end-to-end tests 24x7 to detect bugs and regression. In th...
Widespread fragmentation is stalling the growth of the IIoT and making it difficult for partners to work together. The number of software platforms, apps, hardware and connectivity standards is creating paralysis among businesses that are afraid of being locked into a solution. EdgeX Foundry is unifying the community around a common IoT edge framework and an ecosystem of interoperable components.
"MobiDev is a software development company and we do complex, custom software development for everybody from entrepreneurs to large enterprises," explained Alan Winters, U.S. Head of Business Development at MobiDev, in this SYS-CON.tv interview at 21st Cloud Expo, held Oct 31 – Nov 2, 2017, at the Santa Clara Convention Center in Santa Clara, CA.
Large industrial manufacturing organizations are adopting the agile principles of cloud software companies. The industrial manufacturing development process has not scaled over time. Now that design CAD teams are geographically distributed, centralizing their work is key. With large multi-gigabyte projects, outdated tools have stifled industrial team agility, time-to-market milestones, and impacted P&L stakeholders.

It is of utmost importance for the future success of WebRTC to ensure that interoperability is operational between web browsers and any WebRTC-compliant client. To be guaranteed as operational and effective, interoperability must be tested extensively by establishing WebRTC data and media connections between different web browsers running on different devices and operating systems. In his session at WebRTC Summit at @ThingsExpo, Dr. Alex Gouaillard, CEO and Founder of CoSMo Software, presented ...
WebRTC is great technology to build your own communication tools. It will be even more exciting experience it with advanced devices, such as a 360 Camera, 360 microphone, and a depth sensor camera. In his session at @ThingsExpo, Masashi Ganeko, a manager at INFOCOM Corporation, introduced two experimental projects from his team and what they learned from them.

A strange thing is happening along the way to the Internet of Things, namely far too many devices to work with and manage. It has become clear that we'll need much higher efficiency user experiences that can allow us to more easily and scalably work with the thousands of devices that will soon be in each of our lives. Enter the conversational interface revolution, combining bots we can literally talk with, gesture to, and even direct with our thoughts, with embedded artificial intelligence, whic...

Leading companies, from the Global Fortune 500 to the smallest companies, are adopting hybrid cloud as the path to business advantage. Hybrid cloud depends on cloud services and on-premises infrastructure working in unison. Successful implementations require new levels of data mobility, enabled by an automated and seamless flow across on-premises and cloud resources. In his general session at 21st Cloud Expo, Greg Tevis, an IBM Storage Software Technical Strategist and Customer Solution Architec...
To get the most out of their data, successful companies are not focusing on queries and data lakes, they are actively integrating analytics into their operations with a data-first application development approach. Real-time adjustments to improve revenues, reduce costs, or mitigate risk rely on applications that minimize latency on a variety of data sources. In his session at @BigDataExpo, Jack Norris, Senior Vice President, Data and Applications at MapR Technologies, reviewed best practices to ...
An increasing number of companies are creating products that combine data with analytical capabilities.

When shopping for a new data processing platform for IoT solutions, many development teams want to be able to test-drive options before making a choice. Yet when evaluating an IoT solution, it’s simply not feasible to do so at scale with physical devices. Building a sensor simulator is the next best choice; however, generating a realistic simulation at very high TPS with ease of configurability is a formidable challenge. When dealing with multiple application or transport protocols, you would be looking at some significant engineering investment. On-demand, serverless computing enables deve...
In his session at 21st Cloud Expo, Carl J. Levine, Senior Technical Evangelist for NS1, will objectively discuss how DNS is used to solve Digital Transformation challenges in large SaaS applications, CDNs, AdTech platforms, and other demanding use cases. Carl J. Levine is the Senior Technical Evangelist for NS1. A veteran of the Internet Infrastructure space, he has over a decade of experience with startups, networking protocols and Internet infrastructure, combined with the unique ability to iterate use cases, bring understanding to those seeking to explore complicated technical concepts and ...
"IBM is really all in on blockchain. We take a look at sort of the history of blockchain ledger technologies.

There is a war a-brewin’, but this war will be fought with wits and not brute strength. Ever since Russian President Vladimir Putin’s declaration that “the nation that leads in AI (Artificial Intelligence) will be the ruler of the world,” the press and analysts have created hysteria regarding the ramifications of artificial intelligence on everything from public education to unemployment to healthcare to Skynet. Note: artificial intelligence (AI) endows applications with the ability to automatically learn and adapt from experience via interacting with the surroundings / environment. See the b...
“Why incur the expense of generating and collecting all of this IoT data if you’re not going to monetize it?” Organizations are racing to embrace the Internet of Things (IoT) as the pundits create “visions of sugar-plums dancing in their heads.” McKinsey Global Institute released their study “The Internet of Things: Mapping the Value beyond the Hype” in June 2015 that highlighted the staggering financial value that IoT could create! (See Figure 1.)
Recently I read somewhere this statement – As we end 2017 and look ahead to 2018, topics that are top of mind for data professionals are the growing range of data management mandates, including the EU’s new General Data Protection Regulation that is directed at personal data and privacy, the growing role of artificial intelligence (AI) and machine learning in enterprise applications, the need for better security in light of the onslaught of hacking cases, and the ability to leverage the expanding Internet of Things.
So data warehousing may not be cool anymore, you say? It’s yesterday’s technology (or 1990’s technology if you’re as old as me) that served yesterday’s business needs. And while it’s true that recent big data and data science technologies, architectures and methodologies seems to have rendered data warehousing to the back burner, it is entirely false that there is not a critical role for the data warehouse and Business Intelligence in digitally transformed organizations.
Will I ever understand the nuances of the advanced analytics landscape? Well, maybe the better question is will the advanced analytics landscape ever stop changing? The advanced analytics landscape, into which I include Deep Learning (DL), Machine Learning (ML), Reinforcement Learning (RL) and Artificial Intelligence (AI), seems to be in a constant state of evolution. New advanced analytic algorithms and tool sets seem to be coming out of every university, every startup, every digital media company and every technology company. And many of these new advanced analytic algorithms and tool sets a...

Well, my developer friends, 2018 is your year. Businesses in practically every industry have a fever. And the only prescription? You. I know, I know. The demand for developers is nothing new. But 2018 is different. 2018 is the year where we see some of this decade's most exciting technologies become commercially viable, and others finally go mainstream. We'll see new forms of immersive entertainment, and inanimate objects will come alive in ways that really feel real. Trying to undermine this progress are intelligent and dangerous threats that must be outsmarted and outworked. There's endles...
Since releasing the University of San Francisco research paper on “How to Determine the Economic Value of Your Data” (EvD), I have had numerous conversations with senior executives about the business and technology ramifications of EvD. Now with the release of Doug Laney’s “Infonomics” book that builds upon Doug’s EvD work at Gartner, I expect these conversations to intensify. In fact, I just traveled to Switzerland to discuss the potential business and technology ramifications of EvD with the management team of a leading European Telecommunications company.
Special thanks to Brandon Kaier (@bkaier) for his research and thoughts on the Digital Twins concept. Unilever, one of the Consumer Package Goods (CPG) industry’s titans with over 400 brands and annual sales greater than $60B, recently bought Dollar Shave Club for $1B. Now normally I would not think twice about such an acquisition, peanuts in the world of mergers and acquisitions. However, this one feels different. Two billion people use Unilever products every day according to Unilever’s 2015 annual report. Dollar Shave Club only has around two million members; the vast majority of w...
From government to retail to oil and gas, it seems like everyone is exploring how to use AI in their industry or business. It’s time for you to do the same. There’s no question that Artificial Intelligence (AI) is on a lot of people’s minds these days, and is beginning to grow rapidly in adoption. Quoting Accenture, Forbes reports AI-driven productivity gains of perhaps 40% by 2035, and publications like the New York Times are noting the buzz, even as they ask, why now? Even if you don’t think you’ll be adopting AI for yourself just yet, you need to at least consider the broader impact the te...

This month, an AI (artificial intelligence) system passed a medical exam in China for the first time. I wonder how its bedside manner will be? In addition, Saudi Arabia granted citizenship to a robot named Sophia. With all these rapid advancements, I think it is time we explore the spiritual life of robots. Up till recently, programmers coded and configured algorithms, AI, automation and machine learning system and took personal responsibility for all the code. Today, however, AI has escaped the confines of human oversight and has been empowered and employed to self-program, self-optimize, ...
The Federal Communications Commission announced that it will vote on December 14 to enact the exceptionally misleadingly titled “Restoring Internet Freedom” order. If passed, it will do the opposite of restoring anything resembling freedom — it will repeal the current net neutrality rules which were enacted to ensure that Americans would have equal access to the Internet. If you’re reading this, chances are you’re already interested in the topic. Still, some quick background: Renamed “Open Internet” a while back, net neutrality provided a regulatory framework that specifically prohibited:...
Digital technologies have altered how people and businesses interact. The potential for dislocation from ongoing digital transformation has created unprecedented levels of C-suite discussion. The decisive market leaders have heeded the warnings and taken bold actions. That said, if you’re one of those Chief Technology Officers (CTO) that previously responded to this scenario by making small incremental adjustments to your IT agenda, then you’re potentially at risk. Any relief from those prior tweaks tend to be short lived. The same issues will likely resurface.
Over the last few years, the Internet of things (IoT) has become a trending phrase for consumers and a top priority for businesses embarking on their digital transformation. Even with the growth and interest in IoT however, the meaning can still confuse people. So, what is IoT? IoT is a network of things connected to the internet and is uniquely identifiable through its embedded computing system. These “things” may include a variety of devices like home appliances, commercial vending machines, fitness trackers, industrial gateways, connected cars, and smart factories.
I love it when I get feedback from a blog that I’ve written. I appreciate the different perspectives and insights that others bring to a topic of interest. And no blog that I’ve written has drawn more comments than my blog, “Isaac Asimov: The 4th Law of Robotics.” The section of the blog that fueled the most comments stem from a scene in the movie I, Robot where Detective Spooner (played by Will Smith) is explaining to Doctor Calvin (who is responsible for giving robots human-like behaviors) why he distrusts and hates robots. He is describing an incident where his police car crashed into anot...
