In recent times, organizations have realized that the cost of managing resources in the cloud as the efforts are the same in managing resources, considering security configurations, and other configurations. Hence, IaaS was becoming difficult day by day with the evolution of PaaS. PaaS has evolved over the years and its approach is much wider, and its services include multiple programming languages such as Java, PHP, .NET, Python, and Ruby.
Cloud service providers are responsible for maintaining availability of the application and its resources. Over the years, PaaS has gained its momentum and many organizations have realized that there are less complexities and less management overhead involved in it. With new technology and evolution in organization practices, PaaS is headed towards maturity. Nowadays, aPaaS is getting popular. An Application Platform as a Service (aPaaS) provides features to design, develop, deploy, and manage an application life cycle, enabling effective resource utilization, agility, and faster time to market. While we are considering organization’s best practices or culture, DevOps has also gained momentum in recent times along with PaaS. PaaS and DevOps culture are breaking a lot of barriers in the traditional culture of IT.
DevOps Culture – A Way Forward for Organizations
DevOps is a buzz word nowadays and everyone wants to just jump into it to gain benefits. Let’s understand that it is all about making organization’s culture better with the use of existing set of people, existing or improved set of processes, and existing and or path breaking, innovative, and open source or commercial tools. It helps to develop communication and collaboration between Development and IT Operations teams so as to manage the application life cycle more effectively than the existing ways of doing it.
Make no mistake, this requires CHANGE. Change in mindset and change in the way we have been doing things to manage application lifecycle over the years. It is not an overnight Journey but it is a long, painful yet fruitful journey whose benefits can be realized in the longer span. The DevOps culture involves implementation of source control systems, build tools, CI, cloud computing (service models such as IaaS, PaaS, and SaaS; deployment models such as the public cloud, private cloud, hybrid cloud, and community cloud), containers, configuration management, Continuous Delivery (CD), continuous deployment, continuous feedback, security, governance, and so on.
DevOps with Microsoft Azure
Microsoft Azure is one of the most popular Cloud Service providers available in the market. Microsoft Toolsets provides an easy way to deploy applications having a platform such as Java, .NET, Android, and iOS. The intent of VSTS and Microsoft Azure Cloud Services is to provide agility, scalability, faster time to market, and automation for end-to-end application life cycle management.
The Microsoft Azure application platform services provide application development, repository services, application deployment services, performance testing, security, and governance. The Microsoft Azure App Service is a PaaS used to rapidly build an application that may be web- or mobile-based that can be highly available, scalable, and flexible. Microsoft Azure provides other PaaS offerings—DBMS, App Insights (preview), and so on.
Visual Studio Team Services (VSTS) is a cloud-based service offering from Microsoft that provides the Team Foundation Server (TFS) like version control system. VSTS supports Team Foundation Version Control (TFVC) and the Git repository. VSTS provides hosted agents to execute builds. In VSTS, we can manage CI, continuous testing, or unit testing, and static code analysis in the Build section; performance testing is managed in the Test section; and CD and continuous deployment are managed in the Release section. We can also provide security and governance while configuring release operations of deployment based on the approval system.
To implement the DevOps culture, it is not necessary to use VSTS or Microsoft Azure Public Cloud. It is not about tools. We can also utilize Open Source Automation Server such as Jenkins and we can utilize DevOps for Web Development using AWS public Cloud as well.
Let me reiterate, DevOps is not a tool, technology, model or framework… DevOps is a culture and it is not an overnight journey to implement it.
