Serverless computing is transforming the role of IT operations by allowing developers to focus on writing code while third-party providers manage infrastructure and servers. While serverless computing removes the need for organizations to directly manage servers, IT operations teams still have responsibilities like defining security policies, monitoring the serverless environment, and ensuring secure access to databases. Adopting a serverless architecture is challenging as it requires transforming existing applications but it offers benefits like scaling and a pay-as-you-go model for applications that suit the approach.

1. How is serverless computing transforming the
role of IT ops?
Serverless computing can power technology enabled app delivery. We know that. There
are organizations that still wonder about the role of IT ops if they were to consider
serverless architecture.
If someone asked me a simple definition of ‘serverless’, I will say that it’s a software architecture
wherein the application logic is performed without operating systems, virtual machines, obvious
processes and servers. The service provider is responsible for provisioning and managing the
infrastructure so that the software developer doesn’t have to worry about it. The software developers
can rather focus on writing the code.

Serverless architecture breaks down server-side application into functions responsible for performing
distinct tasks. It lets the complete application to be divided into disparate, loosely coupled components
capable of being operated at a scale that is required.
Software developers think of way of connecting services and functions with the external world. They
typically use a traditional approach that helps them combine several distributed processes at the time of
installation, execution and updating of these processes for precise operating systems that run on some

-party service provider is responsible for
processes, servers and operating systems.
Serverless has become popular, there is no doubt about it. One of the main reasons for its popularity is
due to its AWS’ serverless offering with AWS Lambda and Azure’s functions. This interest grew as it
supports building microservices applications. Serverless can empower in ways more than one. For
example, it adds the ability to calculate each customer transaction
Serverless and the role of IT Ops
In an article titled, Serverless deployment spells fresh opportunities for IT ops, writer Beth Pariseau
explores how serverless computing has a role to play in IT operations even when there are no servers
that are directly managed. It does not imply running the code with the need of a server. It adds another
abstraction layer at server level, adding another layer at which System Administrators must interact with
the systems. It is also called FaaS or Function as a Service. The IT operations team needn’t provision the
code where they need to run the code.
Is there a need for IT ops to manage anything in serverless? Yes, if seen from a DevOps perspective and
if seen it as an application delivery engine that is technology powered. With this understanding of
delivery there are 4 critical aspects – rules, code, configuration, automated infrastructure (infrastructure
as code) and security. The concerned team must define security policies at the time AWS Lambda
functions. For example, System admins should provide secure access to databases through AWS IAM.
It is not possible to become serverless overnight as transforming to it is non-trivial. It is primarily
because of 2 reasons. The first one being that organizations, adopting a microservices architecture, are
gradually moving from code to containers wherein some prefer to turn monolithic apps to smaller
services. Transforming serverless means turning the work they might have done for over 2 decades into
containers first and then transforming to serverless. The second reason is that not all applications will be
suited for serverless architecture. One of the applications that does suit the serverless is Amazon
Lambda (a greenfield app). The business case of applications should also be suitable for a transformation
to serverless besides technology case. Serverless is pay as you go model so it doesn’t make sense for
applications that run round-the-clock.

3. You can’t discount the need to monitor serverless environment itself. The IT ops teams must have to
monitor, add value and analyze serverless architecture constantly.
