The cloud services
Shifting your on-premise IT architecture to the cloud is no easy task, however. Hours and hours of boardroom analysis of your business processes and the need to migrate to cloud gradually is the best way to go about. Before chalking out the migration plan to cloud, it is necessary to understand the cloud services available in the market.
In IaaS, the cloud service provider hosts the hardware, software, servers, network and other infrastructure required for your business in the cloud. The maintenance, backup and disaster management of these components is taken care of by the service provider. IaaS platforms are highly scalable and suited to meet the requirements of businesses with varying workloads.
A Platform-As-a-Service (PaaS) provider hosts the hardware and the software required to run the business application in the cloud. A new application might require the hardware, operating systems, web servers and middleware for it to be deployed. In a PaaS architecture, these underlying software and hardware platforms are supported by the cloud service provider. This is extremely suitable for businesses who do not want to move their entire business process to the cloud.
In the SaaS model of computing architecture, the applications are hosted by the cloud service provider and are made available to customers usually over the Internet. SaaS has gained in immense popularity among businesses across the world, as it can integrate with a wide variety of platforms via web services and with the Internet becoming ubiquitously available, more and more systems are migrating themselves to SaaS. The seamless accessibility through all digital devices across all locations, easy administration, automatic upgrades, collaboration and compatibility are the reasons why SaaS has been able to penetrate the market in a very short span of time.
The cloud platforms
Once you have decided upon which business processes you want to host on the cloud, it is time to decide which type of cloud you want. Typically, most service providers offer a public cloud, a private cloud or a hybrid cloud to host your IT applications.
In a public cloud model, the service provider makes the resources like applications, network and storage available to its customers over the Internet.
Unlike public cloud, a private cloud is dedicated to one single organization and is best suited to businesses which require a direct control of their data hosted in the cloud.
Hybrid cloud offers customers the flexibility to mix the infrastructure among on-premise servers, public cloud and private cloud. The workload can be balanced among these three based on the business demands. This model is highly suitable for changing business needs.
The world of cloud computing provides customers with a wide array of options and great flexibility to choose from.
