Cloud Computing Technology
Cloud computing is a technology to distribute IT resources on demand over the Internet with a policy of paying according to the resources used instead of buying or renting the entire physical server. Cloud services can be used for many scenarios such as data backup, disaster recovery, big data analytics, and web applications for customer interaction.
Cloud computing technology is growing strongly and becoming the leading infrastructure transformation trend of enterprises because of outstanding benefits such as cost optimization; Rapid deployment; Flexible expansion; Increase business productivity…
There are three types of cloud services:
Infrastructure as a Service (IaaS)
Platform as a Service (PaaS)
Software as a Service (SaaS)
The importance of performance in cloud computing
Performance is the most important factor in using cloud services because it directly impacts user experience, business results, competitive advantage, and even the reputation of the business. According to LogicMonitor, 73% of IT professionals cite performance as the top concern when it comes to cloud adoption.
Poor performance can lead to reduced productivity, increased costs, and reduced customer satisfaction, all of which can negatively impact business operations. From a report by global technology company Dynatrace, performance has a significant impact on user experience as 79% of users say they will not return to a slow website.
According to a report by ThousandEyes, a software company, cloud providers experience an average of 13 outages per month, with an average downtime of 45 minutes per outage. This highlights the need for cloud providers to design optimal-performing cloud solutions to ensure business continuity and minimize business outages.
The top three factors driving cloud adoption are scalability, flexibility, and disaster recovery (According to RightScale). These factors are all closely related to performance, as they require the cloud service to be able to handle and adapt to high demand, ensuring business continuity.
Some statistics related to performance in cloud computing
Factors affecting cloud computing performance
The virtual server configuration
The virtual server configuration has the biggest impact on cloud service performance, including vCPU, RAM, and Hard Drive
vCPU: Like the CPU of a physical server, vCPU also includes important parameters to evaluate performance such as the number of cores (cores) or GHz (Clock speed). These are parameters that represent the data processing power of a virtual server. The larger these parameters, the higher the performance the virtual server provides.
RAM: The amount of RAM also significantly affects the performance of cloud services. Cloud services often run multiple processes concurrently. When a cloud service has more RAM, it can support more processes concurrently. This means that the cloud service can handle more user requests concurrently, resulting in more optimal performance delivery.
Hard drive: The larger the storage capacity of the hard drive, the higher the speed of writing and storing data. Currently, SSD hard drives are used more because the data processing speed is superior to HDD.
IOPS (Input / Output per Second): is the total number of Read or Write operations completed in 1 second of the hard drive. For cloud storage devices, IOPS determines the “sensitivity” and “fastness” of the virtual machine. The higher the IOPS, the faster the processing speed, resulting in more tasks being processed. Since then, the performance of applications on Cloud Server is improved.
Network latency indicates the time it takes to transmit data over the network. Networks with fast response times will have low latency. As more and more applications and services rely on cloud computing to perform basic business operations, network latency becomes more and more important and affects the time it takes for users to access cloud services. cloud, resulting in slower performance, which degrades the user experience.
With high bandwidth, data is transferred between the cloud server and the client faster, resulting in fast response times, reduced latency, and therefore performance for enterprise systems. High or low bandwidth depends on the policy and infrastructure strength of the cloud service provider.
Scaling processes in the cloud infrastructure also have a significant impact on performance. There are two types of scaling
Vertical: is the process of scaling by adding resources such as CPU or RAM. Businesses can scale their networks, storage, and computing capabilities. Vertical scaling usually translates into better performance.
Horizontally: in which you add more buttons. This means increasing the number of servers in the current configuration of the business.
The success of a cloud deployment is highly dependent on the practice of comprehensive performance engineering and capacity management techniques. Cloud users or looking for cloud service providers have state-of-the-art monitoring tools to ensure that performance metrics can be continuously collected, analyzed, and evaluated.
