How Does Cloud Computing Work?
Cloud computing is the delivery of computing services such as servers, storage, databases, networking, software over the Internet (“the cloud”) to offer faster innovation, flexible resources and economies of scale. Typically, you only pay for cloud services you use, helping you lower your operating costs, run your infrastructure more efficiently and scale as your business needs change.
ITMS has been providing cloud solutions since 2007. We have industry experience with Amazon (AWS), Google (gCloud), Vultr, Digital Ocean and Microsoft Azure cloud platforms. There are various types of cloud computing and we understand that not all clouds are the same and not one type of cloud computing is right for everyone. Several different models, types, and services have evolved to help offer the right solution for your needs.
These models are public cloud, private cloud or hybrid cloud.
Private Cloud: the cloud services used by a single organization, which are not exposed to the public. A private cloud resides inside the organization and must be behind a firewall, so only the organization has access to it and can manage it.
Public Cloud: the cloud services are exposed to the public and can be used by anyone. Virtualization is typically used to build the cloud services that are offered to the public. An example of a public cloud is Amazon Web Services (AWS).
Hybrid Cloud: the cloud services can be distributed among public and private clouds, where sensitive applications are kept inside the organization’s network (by using a private cloud), whereas other services can be hosted outside the organization’s network (by using a public cloud). Users can them interchangeably use private as well as public cloud services in everyday operations.
why choose cloud?
Benefits of Cloud Computing
Cost
Cloud computing eliminates the capital expense of setting up and running on-site datacenters—the racks of servers, the round-the-clock electricity for power and cooling, and the IT experts for managing the infrastructure.
Performance
Computing services run on a worldwide network of secure datacenters, which are regularly upgraded to the latest generation of fast and efficient hardware. This offers several benefits over a single corporate datacenter, including reduced network latency for applications and greater economies of scale.
Security
Many cloud providers offer a broad set of policies, technologies, and controls that strengthen your security posture overall, helping protect your data, apps, and infrastructure from potential threats.
Speed
Most cloud computing services are provided self service and on demand, so even vast amounts of computing resources can be provisioned in minutes, typically with just a few mouse clicks, giving businesses a lot of flexibility and taking the pressure off capacity planning.
Productivity
On-site datacenters typically require a lot of “racking and stacking”—hardware setup, software patching, and other time-consuming IT management chores. Cloud computing removes the need for many of these tasks, so IT teams can spend time on achieving more important business goals.
Reliability
Cloud computing makes data backup, disaster recovery, and business continuity easier and less expensive because data can be mirrored at multiple redundant sites on the cloud provider’s network.
