Therefore, a serverless application can handle a large number of requests and execute a single request from a single user. A sudden usage increase can impact a traditionally structured app with a specific amount of server space. The term “serverless” was earlier used to define applications incorporating third-party cloud-hosted services and applications to manage server-side state and logic. Serverless can also be defined as applications where the app developers write server-side logic.

Serverless apps are also a good fit for use cases that involve incoming data streams, chat bots, scheduled tasks, or business logic. Serverless architecture is ideal for asynchronous, stateless apps that can be started instantaneously. Likewise, serverless is a good fit for use cases that see infrequent, unpredictable surges in demand. Teams using Serverless systems need to consider operational activities early, and it is on vendors and the community to provide the teaching to help them understand what this means.


The same kinds of problems exist in FaaS land, although there’s been improvement in this area. It’s now possible to run FaaS functions locally for both Lambda and Microsoft Azure. However no local environment can fully simulate the cloud environment; relying solely on local FaaS environments is not a strategy I’d recommend.

Google’s security policies and systems may change going forward, as we continually improve protection for our customers. Google Cloud’s pay-as-you-go pricing offers automatic savings based on monthly usage and discounted rates for prepaid resources.

Serverless Applications Monitoring

Software that require the underlying architecture to be explicitly maintained and unmodified. Security sensitive and offline software use cases in the defense and financial industries often face these requirements to facilitate high application dependability. Serverless database frameworks offer companies room to grow globally, as multiple applications can be developed by region. Still, they all run from one location, powered by FaaS technology. A company’s ability to offer backend services that link a mobile application to the cloud is referred to as BaaS.

The cloud provider is also responsible for all routine infrastructure management and maintenance such as operating system updates and patches, security management, capacity planning, system monitoring and more. With a serverless architecture, developers also won’t have to handle any of the other frustrations that can come with cloud infrastructure oversight, such as container management. Although the serverless approach to cloud app development does involve containers for app functions, these containers are stateless, automated, and managed by the cloud provider. As such, they don’t need container orchestration—though some may opt to use open-source tools to make a container orchestration platform compatible with serverless architecture. The need for effective serverless design patterns increases as more users adopt serverless architecture.

The 3 Critical Steps Towards Preventative Data Security

Being able to breakpoint a remotely running function is a very powerful capability. We’re coming to the end of this journey into the world of Serverless architectures. To close out I’m going to discuss a few areas where I think the Serverless world may develop in the coming months and years. Earlier in the article I mentioned that AWS Lambda functions are aborted if they run for longer than five minutes. This has been consistent now for a couple of years, and AWS has shown no signs of changing it.

This increases your surface area for malicious intent and ups the likelihood of a successful attack. Embracing a Serverless approach opens you up devops predictions to a large number of security questions. Here’s just a very brief smattering of things to consider—be sure to explore what else could impact you.

Application integration

Get the cloud-native strategy guide for architects and IT leaders, including insights to prepare for a serverless approach. I talked earlier about “Serverful” FaaS platform—being able to use FaaS-style architecture for some of our projects, but submitting to compliance, legal, etc. reasons to run our applications on premise. It’s questionable how much value exists in providing a deployment abstraction for multiple platforms though, once complexities of operations rear their ugly heads.

These problems all still exist with Serverless apps, and you’re still going to need a strategy to deal with them. In some ways Ops is harder in a Serverless world because a lot of this is so new. We may want to keep some UX-related functionality in the server, if, for example, it’s compute intensive or requires access to significant amounts of data. In our pet store, an example is “search.” Instead of having an always-running server, as existed in the original architecture, we can instead implement a FaaS function that responds to HTTP requests via an API gateway .

However one could also argue that the ease of provisioning servers may have made the situation worse if a lot of those servers are being left around without adequate capacity management. So far I’ve mostly discussed proprietary vendor products and tools. The majority of Serverless applications make use of such services, but there are open-source projects in this world, too. FaaS offerings do not require coding to a specific framework or library. FaaS functions are regular applications when it comes to language and environment. For instance, AWS Lambda functions can be implemented “first class” in Javascript, Python, Go, any JVM language (Java, Clojure, Scala, etc.), or any .NET language.

This won’t work 100 percent of the time since the cache won’t be warm for every event, but this is the same concern that already exists for traditionally deployed apps using auto-scaling. Deployment is very different from traditional systems since we have no server applications to run ourselves. In a FaaS environment we upload the code for our function to the FaaS provider, and the provider does everything else necessary for provisioning resources, instantiating VMs, managing processes, etc. First usages of the term seem to have appeared around 2012, including in this article by Ken Fromm.
