Cloud services are firmly established in the fabric of IT staff operations as a necessary and growing ingredient of enterprise computing. Infrastructure-as-a-service (IaaS), the most basic form of cloud, is still a key building block, but it is rapidly being supplemented by additional services.
Amazon Web Services (AWS), originator of large-scale public infrastructure self-provisioned by the user, is an example of a basic IaaS gaining layers of services on top. Database-as-a-service (DaaS) is almost a requirement for a competitive, large-scale supplier today.
In addition, services such as real-time data streaming (AWS Kinesis) and an event-triggered software management service (AWS Lambda) become the building blocks of applications needing large-scale compute and storage to handle real-time customer interactions.
While Amazon remains the market leader, it is increasingly challenged by Microsoft, with its large customer base of Windows developers and its Azure Cloud's strength in platform-as-a-service (PaaS). With PaaS, customers get a development environment on which they may build their next-generation applications. That environment then assists them in deploying those applications to the host's IaaS.
