What is reliability in cloud computing?

Reliability in cloud computing is related to cloud technology quality. If the components in a cloud computing service perform their functions and fail rarely, the service is said to be reliable. Thus, when selecting a cloud computing service, it is advisable to look at its reliability. This article discusses the design principles behind reliable cloud computing, the importance of building to scale when it comes to cloud computing, the perceived reliability in cloud computing, and the differences between reliability and availability.

Design principles for reliability in cloud computing

Cloud computing enables delivery of complex systems on a global, resource-sharing scale. Technologies used in cloud computing systems include virtualization, grid computing, and distributed computing, among others.

Always build cloud computing systems with reliability in mind. The following design principles are a helpful guide:

By keeping these design principles in mind, you can minimize the number of times your cloud-based system fails. In case your system does fail, the impact of the failure can be minimized as well.

Importance of scalability in cloud computing

Scalability, or the ability of a system to handle current and future demand, is related to reliability in cloud computing. By incorporating scalability into your cloud computing architecture, you can ensure consistent performance for your users, (regardless of demand), increase or decrease storage capacity when needed, save on hardware and storage costs as well as time, and build fault-tolerant systems.

There are several scalability types in cloud computing, including:

Perceived reliability of cloud computing security

There is a widespread perception that cloud computing security is inherently weak and opens your data to potential attacks from external threats. Many organizations cite this as their primary reason for not moving to the cloud completely.

However, many cloud-based systems are often more secure than their on-premises counterparts. Often, the fault does not lie with the provider when a cloud computing service gets compromised. Rather, users remain the weak points in cloud security, as they fall target to phishing and business email compromises, among other forms of attacks.

This is not to say that cloud computing will forever remain more secure than traditional computing. According to a 2021 IBM report, more malware is being designed to target Linux servers that form the backbone of many cloud computing environments. It is expected that this trend will continue as even more organizations move to the cloud.

Availability vs reliability in cloud computing

Availability, or the amount of time a system is up and functioning properly, is another term associated with reliability in cloud computing. While availability is measured in terms of time loss, reliability is measured in terms of the number and impact of failures. Reliability may be seen as a measure of availability.

When implementing a cloud-based system, organizations must balance their need for availability and reliability with how much they can afford to spend on the system’s components. Typically, they look at service level agreements (SLAs) when choosing a cloud service provider to help them decide if what they are getting is in tune with their needs. Most SLAs stipulate that infrastructure management, security, and troubleshooting and repair, among other factors that influence reliability and availability, are the provider’s responsibilities.

While losses brought about by failure to meet SLAs may be compensated financially, when this is not possible due to factors beyond the provider’s control, credits may be extended to the customers instead. If it is imperative that your systems are up and running all the time, you may want to use redundant and failover systems on your own, instead of relying solely on your provider. Note that this can increase the costs of maintaining your IT infrastructure.

How Parallels RAS helps reliability in cloud computing

Parallels®RAS is the go-to platform when deploying virtual applications and desktops that meet your availability and reliability requirements. Parallels RAS supports the diverse types of cloud computing, including Software as a Service (SaaS), Infrastructure as a Service (IaaS), and Platform as a Service (PaaS), so the platform is perfect if your needs require using any of these models.

Parallels RAS enables convenient access to virtual applications and desktops using any major hypervisor. It supports hyperconverged solutions and (Remote Desktop Session Hosts (RDSHs), enabling application delivery to your end users on any device. It also enables your IT team to provide virtual desktop infrastructure (VDI) desktops and published applications to your end users quickly, aside from allowing automation of other complex and repetitive tasks.

Parallels RAS offers comprehensive security features that meet the demands of larger organizations for secure data access and transmission. Advanced filters, encrypted connections, multi-factor authentication (MFA), and role-based access control (RBAC) are just some of these features. Parallels RAS also supports hybrid cloud deployments.

Parallels RAS comes with a single full license that offers complete access to its suite of virtualization features. Aside from enabling straightforward installation using wizards, its user-friendly interface means that your end users can familiarize themselves with the system quickly.
