IBM Cloud services for you
Cloud hosting can be defined as, hosting on virtual servers which draws its resource from an extensive network of other physical servers. The IBM cloud was recognized as VMware’s 2017 global cloud provider. It emerged with the unification of its virtualization technologies and mainframe computing. IBM’s very first experiment in virtualization happened in 1960’s, by developing the virtual machine. IBM cloud hosting has three hardware platforms for cloud computing. These platforms provide in-built support for virtualization:
IAAS- Infrastructure as a service
PAAS- Platform as a service
SAAS- Software as a service
IBM cloud caters to almost 60 data centers around the world, meeting the needs of the global business. Its customers come from different industries: Finance, Education, Healthcare, Technology, and Retail
Cloud computing comes in three forms: Public cloud, Private cloud and Hybrid cloud
Public cloud computing
Public cloud hosting makes use of cloud models open to public; hosting on virtual servers which make use of resources from other available public servers.
The data is transmitted from the same public networks. This data is stored physically in the underlying shared servers which is a part of the cloud resource.
Security measures are taken to ensure the data is private for these public clouds, and would be adequate for most installations.
Private cloud computing
- Private cloud is primarily managed through internal resources.
- In comparison to public cloud, private cloud is more maintain more security and privacy with their services.
- Both the terms Private cloud and virtual private cloud terms are used interchangeably.
Public versus Private cloud computing
Virtualized resources are publicly shared Virtualized resources are privately shared
It supports and serves multiple customers it serves a group of dedicated customers
Best suited for less confidential information confidential information and core systems are secured
Public cloud supports internet connectivity Private cloud supports internet, fiber and private network
The advantage of private and public cloud more or less serves the same purpose, in terms of scalability, proprietary architecture and self-service. The only major difference between the two: Private cloud delivers service fulfilling the needs and goals of a single organization and public cloud delivers service to multiple organizations.
Hybrid cloud computing
Hybrid cloud computing is an environment where, public cloud and private cloud are combined by orchestrating the data and applications between them. Hybrid cloud computing gives the business the capacity to level-up the public cloud with infrastructure on-premises in lieu to hold the overflow by securing their data entirety to third party datacenters. Hybrid cloud benefits the businesses in organizations by offering them with flexibility and deployment options.
Benefits of hybrid cloud
- it’s useful for dynamic and highly varying workloads.
- It enables an enterprise to use a broader mix of IT services.
- It provides improved connectivity by when moving business components to the cloud.
