What is Edge Computing? 

Edge computing is a term used to describe decentralized IT infrastructure. In an edge computing environment, applications, computation, and data storage are all carried out near the source of the data (i.e. at the “network edge”), as opposed to in the cloud or at an offsite datacenter. By processing data locally and minimizing the distance between devices and servers, edge computing delivers improved performance, requires less bandwidth, and reduces latency.

How Does Edge Computing Work? 

Traditional IT infrastructure requires data to be transmitted across lengthy distances and multiple network connections, which may require substantial bandwidth and hardware. Edge computing brings compute and storage resources closer to where the data is generated, reducing the distance it has to travel. Rather than sending the data off to the cloud, or pushing it to a central datacenter, it allows for real-time processing of applications within close physical proximity to the end user. 

Through the use of virtualization technology and software-defined storage, edge computing enables users to deploy and run their applications, while ensuring high availability, through software installed on their edge servers. For compute-intensive environments, organizations can implement a hybrid compute model, where high-demand applications are processed near the source and others are transmitted to a central datacenter location.

What Are the Benefits of Edge Computing? 

Many organizations today are creating massive amounts of data, requiring fast transfer rates and response times, which often aren’t feasible when it comes to traditional IT infrastructure. Edge computing solutions offer several user benefits, including: 

High Availability 

Downtime and slow response times are detrimental to businesses, resulting in decreased productivity, damage to brand reputation, and even loss of revenue. Edge computing can ensure high availability for applications and data, by leveraging a virtualized shared storage solution such as a virtual SAN on the hardware at the edge site. A highly available configuration can eliminate downtime, which keeps vital applications online, productivity high and customers satisfied. 

More Affordable 

As businesses grow, edge computing enables them to scale more cost-effectively. The hardware required at edge sites costs less - it doesn’t have to be datacenter-class, and the organization often does not need to install costly high capacity networking links for additional bandwidth and mitigate against latency. As well as latency, edge computing also helps mitigate against another common IT problem that can significantly impact revenue: downtime.  

Increased Reliability 

With traditional datacenter models, data is processed and stored centrally, and an outage at that central location is therefore much more likely to affect the entire organization. Edge computing reduces the threat of such scenarios by decentralizing resources, allowing each site to operate effectively on its own, minimizing the damage of network issues. Distributing applications, processing, and storage makes it more difficult for a single disruption, such as a localized natural disaster, to take down the entire organization. 

Several different types of environments benefit from implementing edge computing solutions, including remote and branch offices, retail stores, industrial IoT, and manufacturing sites.

SvSAN and Edge Computing

StorMagic has been building and delivering solutions for the edge for over a decade. SvSAN was built specifically to address the needs of edge computing environments, providing increased uptime, simplicity, and extreme low cost for edge customers, without sacrificing performance or enterprise-class features.  

Here are some of the benefits SvSAN offers edge computing sites: 

vSAN vs SvSAN

Simple

Set and forget

Edge customers are able to deploy 1000 sites as easily as a single site using SvSAN. It provides effortless high availability through synchronous mirroring between two nodes, and eliminates single points of failure. It allows for centralized deployment and management, through automation tools and scripts, which enables any IT professional to operate the solution, regardless of experience or skill set. 

Cost Effective

Lightest footprint, lowest cost

With SvSAN, organizations are able to eliminate the use of physical SANs, resulting in dramatically lower costs. All that’s required at each site are two servers with a single lightweight witness providing quorum for up to 1000 clusters, which significantly lowers both CAPEX and OPEX. It also helps eliminate downtime (planned and unplanned), by allowing for seamless upgrades without impact on day-to-day operations.

Flexible

Today’s needs, future proofed

SvSAN supports any environment and configuration. It enables edge computing sites to utilize any two x86 servers with any storage type to meet their needs. It also allows for easy growth in the future, by eliminating overprovisioning and enabling non-disruptive hardware and software upgrades. With SvSAN, edge customers are able to easily scale-up capacity or scale-out performance to meet evolving business demands.
