In a rapidly changing technology environment, business users are looking at simple and secure applications that can be accessed at anytime, anywhere and on any device. These applications should be engaging, integrated, mobile compatible, available on net and cloud based. Cloud computing is a short label, but it describes a vast array of business models, technologies and services. At the simplest level, cloud computing enables IT capabilities to be delivered as a service to users via the Internet.
Vachi Info Tech 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.
Infrastructure as a Service (IaaS)
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.
Platform as a Service (PaaS)
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.
Software as a Service (SaaS)
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
- Azure deployment
