What Is Function-as-a-Service? Serverless Architectures Are Here
By Matt Watson
It has never been a better time to be a developer. Thanks to cloud computing, deploying our applications is much easier than it used to be. How we deploy our apps continues to evolve thanks to cloud hosting, Platform-as-a-Service (PaaS), and now Function-as-a-Service.
What Is Function-as-a-Service (FaaS)?
FaaS is the concept of serverless computing via serverless architectures. Software developers can leverage this to deploy an individual "function", action, or piece of business logic. They are expected to start within milliseconds and process individual requests and then the process ends.
Principles of FaaS:
- Complete abstraction of servers away from the developer
- Billing based on consumption and executions, not server instance sizes
- Services that are event-driven and instantaneously scalable

At the basic level, you could describe them as a way to run some code when a "thing" happens. Here is a simple example below from Azure Functions. Shows how easy it is to process an HTTP request as a "Function".
using System.Net;
public static async Task<HttpResponseMessage> Run(HttpRequestMessage req, TraceWriter log) {
log.Info("C# HTTP trigger function processed a request.");
// Get request body
dynamic data = await req.Content.ReadAsAsync<object>();
return req.CreateResponse(HttpStatusCode.OK, "Hello " + data.name);
}
Benefits & Use Cases
Like most things, not every app is a good fit for FaaS.
We have been looking to use them at Stackify primarily for our very high volume transactions. We have some transactions that happen hundreds of times per second. We see a lot of value in isolating that logic to a function that we can scale.
- Super high volume transactions - Isolate them and scale them
- Dynamic or burstable workloads - If you only run something once a day or month, no need to pay for a server 24/7/365
- Scheduled tasks - They are a perfect way to run a certain piece of code on a schedule

Types of Functions
There are a lot of potential uses for functions. Below is a simple list of some common scenarios. Support and implementation for them varies by provider.
- Scheduled tasks or jobs
- Process a web request
- Process queue messages
- Run manually
These functions could also be chained together. For example, a web request could write to a queue, which is then picked up by a different function.
FaaS Providers
AWS, Microsoft Azure, and Google Cloud all provide a solution. A lot of innovation is still going on in this area and things are rapidly improving and changing. Read our article on how AWS, Azure, and Google Cloud compare to determine which cloud best meets your needs.
Monitoring Challenges
One of the big challenges is monitoring your function apps. You still need to understand how often they occur, how long they take, and potentially, why they are slow.
Since you don't necessarily have a server or control the resources they are running on, you can't install any monitoring software.
How we monitor these new types of apps is going to continue to evolve.
Comparing FaaS vs PaaS
Platform-as-a-Service greatly simplifies deploying applications. It allows us to deploy our app and the "cloud" worries about how to deploy the servers to run it. Most PaaS hosting options can even auto-scale the number of servers to handle workloads and save you money during times of low usage.
PaaS offerings like Azure App Services, AWS Elastic Beanstalk, and others, make it easy to deploy an entire application. They handle provisioning servers and deploying your application to the servers.
Function-as-a-Service (FaaS) provides the ability to deploy what is essentially a single function, or part of an application. FaaS is designed to potentially be a serverless architecture. Although, some providers, like Azure, also allow you to dedicate resources to a Function App.
When deployed as PaaS, an application is typically running on at least one server at all times. With FaaS, it may not be running at all until the function needs to be executed. It starts the function within a few milliseconds and then shuts it down.

The purpose of this article is draw attention to key SaaS services that are commonly overlooked during contact signing that are essential to ensuring they meet the expectations and requirements of the organization and provide guidance and recommendations for process and controls necessary for achieving quality SaaS contractual agreements.
The first step to solving a problem is recognizing that it actually exists. And whether you've realized it or not, cloud services are a problem for your IT department.
Even if you feel like you have a solid grasp of cloud technology and the nuances of making a cloud purchase, business leaders don't share the same confidence. Nearly 80% feel that IT lacks the skills necessary to help with cloud purchases-and they're looking to cloud brokers for help instead.
It's time to admit we have a cloud services problem and start adapting to modern business technology. Part of that is understanding whic...
According to a recent Gartner study, by 2020, it will be unlikelythat any enterprise will have a “no cloud” policy, and hybrid will be the most common use of the cloud. While the benefits of leveraging public cloud infrastructures are well understood, the desire to keep critical workloads and data on-premise in the private data center still remains. For enterprises, the hybrid cloud provides a best of both worlds solution. However, the leading factor that determines the preference to the hybrid cloud, among other things, is “security.” Moreover, as the growth of the public cloud infrastructure...
In this modern world of IT, you've probably got some new colleagues in your life-namely, the cloud and SaaS providers who now hold your infrastructure in their hands.
These business relationships-yes, they're technology-based, but cloud and SaaS are business models-will become as important to your IT team and your company as the hardware and software you used to install. Once you've adopted SaaS, or inherited SaaS, it's on you to avoid price hikes, licensing issues and app or provider sprawl. Budgeting for these apps, which means understanding their pricing models, is also likely in IT's ha...
Google's Cloud team this week discussed multicloud integration with their own platform and AWS using Google Cloud Endpoints and AWS' Lambda. The Cloud Endpoints let you develop open APIs, and you can then call those APIs up from Lambda. This may be the way forward for businesses eager to get their multiple public cloud providers integrated. We're interested in the network dependency that's now been introduced as the two providers connect. We'll see what other integration or multicloud management tools come out as this trend grows.
IT leaders have always had their hands full with ghost issues on-premises. But for businesses that rely on remote and branch offices, monitoring a sprawling network of on-premises equipment introduces even more challenges.
That's why we move to the cloud, right? To help us eliminate truck rolls, improve cost efficiency and centralize management of applications across all locations.
When you've migrated to the cloud (even if it's just for something like office applications like Office 365 or G Suite), you've already considered compliance, licensing, budget concerns. But what happens when yo...
As more organizations move to the public cloud, they face an important decision: Should they use just one cloud provider, such as Amazon Web Services (AWS), or should they adopt a multi-cloud strategy, one that makes use of multiple cloud providers?
There are several major cloud platform providers, including AWS, Microsoft Azure and Google Cloud Platform. The advantage of a multi-cloud strategy is that organizations can reap significant benefits by using the best of different platforms, rather than relying on a single provider for all of their cloud needs.
Have you ever had the feeling of Silicon Valley envy? Think of a company like Airbnb experiencing exponential growth by making the most of AWS cloud computing. It would be nice if we could all just leave our legacy-laden on-premises data centers behind and go all-in on the cloud.
Traditional businesses are moving more and more workloads to the cloud, but there's one important distinction to keep in mind when comparing yourself to companies that have avoided on-premises infrastructure.
To more closely examine the variety of ways in which IT departments around the world are integrating cloud services, and the effect hybrid IT has had on their organizations and IT job roles, SolarWinds recently released the SolarWinds IT Trends Report 2017: Portrait of a Hybrid Organization. This annual study consists of survey-based research that explores significant trends, developments, and movements related to and directly affecting IT and IT professionals.
A Man in the Middle attack, or MITM, is a situation wherein a malicious entity can read/write data that is being transmitted between two or more systems (in most cases, between you and the website that you are surfing). MITMs are common in China, thanks to the “Great Cannon.”
The “Great Cannon” is slightly different from the “The Great Firewall.” The firewall monitors web traffic moving in and out of China and blocks prohibited content.
The Great Cannon, on the other hand, acts as a man in the middle and is not just able to eavesdrop on the conversation taking place between two or more syste...
When you decide to launch a startup company, business advisors, counselors, bankers and armchair know-it-alls will tell you that the first thing you need to do is get funding. While there is some validity to that boilerplate piece of wisdom, the availability of and need for startup funding has gone through a dramatic transformation over the past decade, and the next few years will see even more of a shift.
A perfect storm of events is causing this seismic shift. On the macroeconomic side this storm includes the still-persistent repercussions of the Great Recession, historically low interest ...
In the famous comedy by William Shakespeare, “The Taming of the Shrew,” the main plot depicts the courtship of Petruchio and Katherina, the headstrong, uncooperative shrew. Initially, Katherina is an unwilling participant in the relationship, but Petruchio breaks down her resistance with various psychological torments, which make up the “taming” — until she finally becomes agreeable.
An analogous challenge exists when using predictive analytics with healthcare data. Healthcare data can often seem quite stubborn, like Katherina. One of the main features of healthcare data that needs to be “tam...
