Introduction to cloud servers and their benefits – Part 2: Scalability and reliability

By | October 11, 2018

After describing in the first part of this article which servers are in the cloud and how they work in the context of cloud computing, the following rates describe how to generate some of the key features that motivated cloud adoption to be more personal as well. Promote at the company level. This part includes the benefits of scalability and reliability related to performance.

expansion capacity
By combining computing power with a large number of servers in the cloud, cloud service providers can offer highly scalable services with no specific functionality. With hypervisor software that gets resources from a large number of core servers when needed, cloud services can meet demand, so the growing demand for cloud services for customers can be satisfied immediately . the computing power needed. The functionality is not a problem, it depends on the capacity of the server. As a result, customers must request additional servers and configure them as demand grows. In addition, for cloud services where the product is already deployed, the client can easily access the service at no cost and delay the initial configuration of the server.

For customers whose IT functionality has significant usage fluctuations, for example. For example, with variable traffic sites, cloud cloud server resource eliminates the possibility of service disruption when demand increases dramatically. On the other hand, it is not necessary to invest in high capacity configurations, in case of emergency for these increases, which will not be used for a long time. As the customer’s demand decreases, the resources he uses (and pays) can also be reduced.

Reliability – redundancy and availability
As mentioned earlier, the large number of cloud servers used to create the cloud service offering reduces the risk of service disruption due to performance issues or downtime related to high demand. However, the form also protects against individual error points. When a server without an Internet connection is disabled, the service it has contributed to is not disabled because there are many other servers that provide this resource. In some cases, physical servers reside in different data centers, even in different countries, where a serious failure can cause the data center to run without failing the cloud service. In some ways, backup operations are created in different data centers specifically to combat this risk.

In addition to unexpected errors, a clustered server resource can also enable maintenance (for example, patching to operating systems) on servers and networks without disrupting or disrupting the cloud service. In addition, maintenance and other support activities that improve the performance, security and stability of cloud servers are performed by dedicated and experienced staff working for the cloud provider or hosting provider. In other words, end-users are not obliged to invest to acquire this experience on their own and instead can focus on end product performance.
