Vachi Infotech is a proponent & early adopter of cloud platform. With highly skilled professionals, we help clients in selecting the best cloud computing model (public, private or hybrid) and platform type (Azure and Amazon). We develop new cloud apps, customize or migrate existing applications and post-implementation model provides a roadmap for clients in managing their applications and infrastructure.
Cloud services are frequently divided into three categories – "IaaS", "PaaS" and "SaaS", although this should not be taken as a finite categorization.
These services typically provide users with virtual infrastructure, such as a platform virtualization environment and ancillary storage and networking functions. Such services can be paid for on an "as used" basis, similar to other utilities such as water or electricity.
This category of cloud computing sits between IaaS and SaaS. Cloud platforms include not only virtual infrastructure but also cloud application environments (and applications). Users can operate PaaS services to create and operate bespoke applications.
These services offer users access to software programs without the need to locally install and run the software. This reduces the need for each user to have their own high level computing capabilities and often also reduces maintenance costs.
Cloud services normally divide between public and private clouds - the former open to all, and the latter managed by or specifically for the organizations they serve – or some combination of those resources. The following diagram distinguishes features of some typical cloud scenarios:
|Public Cloud||Private Cloud||Corporate IT System|
|Applications and content||Software as a service||Infrastructure, Software and Software as a service||Corporate services|
|Development platform||Platform as a service||Platform as a service|
|Infrastructure, Software and Hardware||Infrastructure as a service||Infrastructure as a service|
|Run by cloud provider||Run by cloud provider||Run by customer for select group of users|
|Shared, multi-tenant offering||Dedicated environment for a customer or a group of customers||No sharing with other customers|
|Standard Solutions||More customization possible|
