Question - What is PaaS in Cloud Computing?
Answer -
Platform as Service, abbreviated as PaaS, is the runtime environment for developers to create, test, run and debug web applications. We can easily buy these web applications from the cloud service provider on a pay-as-you-go basis and access them easily using the internet. There is back scalability which the cloud service provider manages, so end users do not need to worry about managing the infrastructure.
PaaS includes infrastructure, servers, storage and networking, platform-middleware, development tools, database management systems, and business intelligence to support the web application life cycle.
PaaS providers support programming languages, Applications frameworks, Databases, and other tools.
Advantages of PaaS in cloud computing
Simple Development: Paas allows developers to focus on development and innovation without worrying about infrastructure management.
Lower Risk: No need for investment in hardware equipment and software.
Prebuilt business functionality: Some Paas Providers have a prebuilt framework so that users do not need to build everything from scratch and can directly start projects.
Instant Community: PaaS vendors have a community where developers can share experiences.
Scalability: Applications deployed can scale with one user
Disadvantages of PaaS in Cloud Computing
Vendor lock-in: Development according to the particular vendor can be easy, but migration to another cloud provider can be a problem.
Data privacy: Corporate data, whether can be essential or not, will always be private, and it should always be an insecure environment.
Synchronization of system applications: We have integrated many applications with local and on the cloud, so there is the problem of increased complexity when mixing local data with cloud data.
