Platform-as-a-Service (PaaS) providers offer an attractive proposition for enterprises looking to reap the benefits of cloud delivery models. By offering a stack of re-usable software and service management components — such as load balancing for Web applications or automated back-ups and patching of databases — PaaS offerings can help accelerate time-to-market with new developments, simplify ongoing maintenance, and further strengthen the economies of scale inherent in Infrastructure-as-a-Service (IaaS) delivery models.However, to select the right PaaS provider each enterprise will need to create a structured set of requirements against which to judge the different offerings.
This paper will:
- Analyse some challenges that financial institutions face in PaaS adoption and outline architectural techniques to address those challenges.
- Outline the selection criteria that firms should use to evaluate their providers, including functional and non-functional capabilities, ease of integration, as well as capabilities aimed at addressing risk, security and compliance requirements.
- Provide a summary evaluation of the capabilities offered by leading web application and database PaaS providers, including Amazon Web Services, CenturyLink, Engine Yard, Google, Heroku, Microsoft, RackSpace and RedHat OpenShift.
