Achieving Application Portability with PaaS

Today, Platform-as-a-Service (PaaS) is increasingly gaining popularity as a Public Cloud offering compared to Infrastructure-as-a-Service (IaaS) because of its simple operations and lower costs. These days, most PaaS customers get locked-in because of the specialized OS or middleware features but for the customers looking for flexibility in working across multiple Cloud platforms and providers, a portable PaaS environment is a feasible choice.

Before we see how organizations can implement a portable PaaS model, let’s first see the primary reasons behind the adoption of PaaS services:

  • Lesser costs of licensing and supporting because of the pre-installed OS and middleware.
  • Streamlined Hybrid Cloud deployment with standardized application services.
  • Improved application performance and functionality by creating a PaaS environment within the IaaS Cloud using the available web services.

How a portable PaaS model fairs across these three areas and how it moves within the various cloud and private environments is important but a single PaaS approach might not be enough to address this. Thus, enterprises need to prioritize their PaaS goals and combine different options to create the desired PaaS environment.


Here are the top 4 ways to achieve a Portable PaaS model:

Adopt Container Technology for Application Hosting: The container architectures share the Operating System, but the middleware and file system elements can be copied to each container to standardize the middleware across container images. This allows the creation of specialized container images for the application and the component which can then be moved across environments to be run on any container system hosted in Cloud or the Data Center.

Sysfore Case Study – SAP on Microsoft Azure

This case study is on a  global technology consulting firm, focused on leveraging emerging technologies for innovation and application modernization in Banking & Finance, Utilities, CPG, Retail, Technology, Media and Entertainment Industries. It partners with companies to identify new technology strategies to help businesses transform, in order to advance performance and competitiveness. They have over 100 clients globally.


A Global Technology Consulting firm used Microsoft Azure to migrate their existing SAP workload to the cloud, offering them redundancy, flexibility and scalability.

Business Needs:

The client’s internal and external training programs and demos use SAP IDES (Internet Demonstration & Evaluation System), which are demo systems running SAP modules and applications for training purposes. Accessing these internal training programs across different global locations posed hurdles in connectivity as their standalone SAP servers were unreachable and lacked redundancy/fault tolerance. Implementing SAP on-premise brought additional challenges like delays, security, scalability and capacity planning.

DevOps on the AWS Platform

DevOps on AWS has always been a critical business decision for many businesses. Its becoming important for businesses to analyse when to use native tools and applications and when they need to turn to a third party partner to help them manage their infrastructure, especially if they are opting to use the public cloud for their devops strategy.

AWS has two key features like scalability and API automation which makes it the go to platform for a DevOps model. However, the challenge arises when enterprises using legacy systems for the longest time, treat Ops as a secondary decision in the business.

Sysfore Technologies, a Bangalore based cloud management provider and AWS partner, helps businesses move to DevOps on AWS.

Sysfore’s transition from web hosting to cloud computing, and shifting from  siloed working groups to DevOps, took some years to implement. We had many challenges from customer demand for newer services and getting people with the right skill set to gain the internal expertise required to manage this platform. But today, we have seen immense growth and we keep adding new products, services and functionalities in our AWS portfolio .Says Ajith Mathew George- CTO- Sysfore Technologies.
