From being a shiny silver lining, Cloud has moved to business-as usual-for most enterprise organizations.
In its simplest form, cloud computing allows companies to procure technology as services, including infrastructure, applications, platforms and business processes, via the Internet. Becoming digital is a priority for nearly every business on the planet.
There are 3 levels of Cloud computing
SaaS – Software as a service:
- Software that is deployed over the internet and accessed via a web browser
- Software vendor maintains the servers, databases and code for each application
- Geared towards end users
- Already trusted by many organizations for non-critical business apps like Payroll, HR, CRM
IaaS: Infrastructure as a service
- Maintain control of software environment without maintaining any equipment
- Hardware like storage, servers, networking is outsourced
- Service provider responsible for housing, running and maintaining
PaaS: Platform as a service
- Provides tools and services to develop a platform
- Develop new application or service independent of any technology and made available on the web
Top cloud service providers are Amazon Web services, Microsoft Azure & Google Cloud.
The ability to scale up and scale down, enables digital without the burden of over provisioned costs. Cloud can reduce the costs up to 25% and can form the foundation for digital transformation.
Today Big data, Analytics are by default coming up on cloud to exploit scale and speed at less costs.
Cloud computing comes in three forms: public clouds, private clouds, and hybrid clouds. Depending on the type of data you're working with, you'll want to compare public, private, and hybrid clouds in terms of the different levels of security and management required.
Public Clouds : A public cloud is one in which the services and infrastructure are provided off-site over the Internet. These clouds offer the greatest level of efficiency in shared resources; however, they are also more vulnerable than private clouds.
Private Clouds: A private cloud is one in which the services and infrastructure are maintained on a private network. These clouds offer the greatest level of security and control, but they require the company to still purchase and maintain all the software and infrastructure, which reduces the cost savings
Hybrid Clouds: A hybrid cloud is a combination of public and private clouds allowing IT organizations to become a broker of services - some they provide on their own and some they procure from public cloud sources.
Cloud doesn’t just deliver reduced costs. Other significant business benefits can also be realized by adopting cloud to include quicker, easier procurement, improved quality of service and greater security.
