At a Glance
Integration of DevOps throughout the development process of SaaS Applications allows the entrepreneur to leverage various benefits, including quicker development and superior customer experience. Without SaaS DevOps, most service providers will struggle to leverage the scope of the technology to the fullest.
In the last few years, there has been an increasing curiosity around DevOps and how it has been transforming businesses globally. Engineers are reskilling themselves to be able to master this promising technology. But what exactly is DevOps? What is its significance in present times? What does the future of DevOps look like? Let us have a look into the world of SaaS DevOps and understand its significance for modern businesses. But first, understand the various cloud technologies available for modern developers.
Prominent Cloud Technologies
Cloud Computing is on-demand provisioning of the resources available with a pay-as-you-go subscription. Its flexibility, ease of use, and scalability makes it useful for DevOps. Its three main models are: –
1. Infrastructure as a Service (IaaS)
It is the delivery of computing resources like data storage and networks to end-users through a service model.
2. Platform as a Service (PaaS)
It allows consumers to deploy and run applications on the platform. It eliminates the need for system administration completely.
3. Software as a Service (SaaS)
It delivers products to end-users via the internet and via pay-as-you-go pricing in which the software provider manages the software.
Out of these three cloud technologies, SaaS is regarded as the most compelling option. The reason being its ability to transfer the bulk of the technical support expenses and facilitate direct selling to the customers. By integrating DevOps with SaaS, entrepreneurs can automate the development process and significantly reduce their expenses involved.
What is SaaS DevOps?
DevOps refers to software development practices that help the development cycle to shorten while also retaining enterprise-grade quality control. When it comes to SaaS, DevOps can be both a methodology and a profession.
As a Methodology
It includes a combination of philosophies, tools, and practices related to software development as well as IT operations, Dev, and Ops, respectively. DevOps accelerates the delivery of software products. When the pace of development increases, organizations can reduce their SaaS products’ time to market and thus satisfy the needs of the customers in a better way. It relies on the people who have historically operated in separate organizational silos – the development and the operations team. Together they become the ‘SaaS DevOps’ team.
As a Profession
A person who takes on SaaS DevOps as a profession, for instance, a SaaS DevOps engineer, will be a person who is going to be responsible for both the reliability of the software (Ops) and the pace of its development (Dev). It is more like a multidisciplinary role that consists of a wide range of duties that have been performed by individuals before system administrators, release engineers, and software developers. Such engineers implement continuous integration and continuous delivery process, automate software build and deployment routines, and manage the cloud infrastructure.
Site Reliability Engineering
An SRE is a concrete class that implements a DevOps interface. The following quote perfectly sums up the purview of SRE.

CI/ CD- The Backbone of SaaS DevOps
CI is a software development procedure in which developers incorporate source code changes into the shared repository as soon as possible, several times a day. Each integration invokes building, testing, and verification of the code change. CI allows developers to locate and eliminate software defects early on during the life cycle of the product, which further accelerates development speed.
CD, i.e., Continuous Delivery, is a further extension of the CI in which the software is ready to be produced at any time. It includes fully automated release deployment, which speeds up the development process further.
CD, i.e., Continuous Deployment is the superlative form of software development practice. Continuous Integration and Delivery are extended to their extremes. The software is released here as soon as any sort of change is produced by the developer, multiple times a day.
TDD and Microservices: SaaS DevOps Strategies
· Test-Driven Development, or TDD, is a software development procedure that needs software engineers to write automated tests before writing the actual code, which will then be validated by the tests. A short development cycle is followed while implementing TDD: –
– Writing an initially failing automated test to serve as a specification,
– Ensuring that the test fails,
– Writing the minimum amount of code for the test to pass,
– Refactoring the code, and
– Repeating the cycle.
It reduces the risks of software bugs with each individual release, which makes it possible to release the product confidently, quickly, and more often.
· Microservices refer to the architectural approach in software development. The complex applications are formed as a collection of loosely coupled and small services. Microservices and DevOps complement each other quite well since it is easy to build continuous delivery channels for autonomously developed, tested, and deployed microservices. This is a big draw from the standard practice of configuring a continuous delivery pipeline for a large monolith in one stroke. Smaller companies tend to deliver faster than their bigger counterparts.
· Virtual Machines are simple emulations of the physical computer machines that we have. It has revolutionized software development, accelerated provisioning time for computer machines. It reduces the time required to provision a computer machine from several days to a few seconds.
SaaS DevOps Infrastructure
A Docker Container bundles the application source code and required dependencies in a single unit so that it can be easily deployed in any environment.
Kubernetes is an open-source system to automate the management of containerized applications.
Infrastructure as Code (IAC)
It is the infrastructure management approach in which resources like networks and servers are provisioned and managed through machine-readable definition files.
Augmenting one’s team with managed SaaS DevOps allows one to harness the skills and experience of multiple solution architects and leverage SaaS DevOps strategies without incurring any significant expenses in the long run.
