Cloud Computing Basics—Platform as a Service (PaaS)

Security in PaaS

It is essential that application developers are thoroughly experienced in application security best practices. This can include secure coding practices in the proffered language as well as in secure design principles. Unlike traditional application development, PaaS offers a shared development environment, so authentication, authorization and access control can be combined to ensure consumers' data and application security. It is also important to scan Web applications for common security issues, such as cross-site scripting (XSS) and SQL injection. To refine development efforts to produce secure and robust applications, application threat modeling is critical. OWASP threat modeling can be used to create secure applications.

Future of PaaS

Many IaaS providers are moving up in the stack of service models. AWS is one of the examples. Today, the market for PaaS may be the smallest proportion of the overall public cloud. But, it will have huge implications in application developers' roles and responsibilities. Nearly half of respondents (49.6%) to the 2013 TechTarget Cloud Pulse Survey said they chose the PaaS they did because it was part of a cloud ecosystem they already were using. Similarly, 43% of respondents said they based their decision on how well the PaaS would integrate with existing architecture. Now, PaaS providers have realized that it will be more beneficial from a market and competition point of view to run services across several IaaS providers' architectures. Some providers are providing private versions of their PaaS offering, so organizations can use the same services in their existing facilities to utilize existing resources in a better manner.

According to 451 Research, PaaS is the fastest growing area of cloud computing and is projected to attain a 41% compound annual growth rate (CAGR) through 2016—24% of total cloud revenues.
