Cloud Computing
Our experience teaches us building the infrastructure to support cloud computing now accounts for more than a third of all IT spending worldwide. Meanwhile spending on traditional, in-house IT continues to slide as computing workloads continue to move to the cloud, whether that is public cloud services offered by vendors or private clouds built by enterprises themselves.
VDS provides solutions in the below areas of cloud computing.
SaaS
Software-as-a-Service (SaaS) is the delivery of applications-as-a-service, probably the version of cloud computing that most people are used to on a day-to-day basis. The underlying hardware and operating system is irrelevant to the end user, who will access the service via a web browser or app; it is often bought on a per-seat or per-user basis.
IaaS
Infrastructure-as-a-Service (IaaS) refers to the fundamental building blocks of computing that can be rented: physical or virtual servers, storage and networking. This is attractive to companies that want to build applications from the very ground up and want to control nearly all the elements themselves, but it does require firms to have the technical skills to be able to orchestrate services at that level.
PaaS
Platform-as-a-Service (PaaS) is the next layer up — as well as the underlying storage, networking, and virtual servers this will also include the tools and software that developers need to build applications on top of: that could include middleware, database management, operating systems, and development tools.
Future of cloud computing
Cloud computing is still at a relatively early stage of adoption, despite its long history. Many companies are still considering which apps to move and when. However, usage is only likely to climb as organizations get more comfortable with the idea of their data being somewhere other than a server in the basement. We’re still relatively early into cloud adoption — some estimates suggest that only 10% of the workloads that could be moved have actually been transferred across.
