Hey there,
PaaS Advantages
· PaaS-built software is highly scalable, available and multi-tenant, as it is cloud-based
· The development process is quickened and simplified
· Reduced expenses for creating, testing and launching apps
· Automated company policy
· Reduced amount of coding required
· Allows for easy migrating to the hybrid cloud
PaaS Disadvantages
· Data security issues
· Compatibility of existing infrastructure (not every element can be cloud-enabled)
· Dependency on vendor’s speed, reliability and support
