The IT marketplace is in constant flux. Consumer and enterprise product offerings change on a regular basis. Products are launched. Others are retired. Sometimes it feels like new terminology enters the computing lexicon every day. For busy professionals charged with the delivery of a secure, robust network infrastructure, it pays to stay up to date with current terms. In addition to this article, our Glossary at https://kemptechnologies.com/glossary/ is a dynamic resource that defines key terms related to application delivery networks.
Application Delivery Controller (ADC) – The ADC takes processor intensive tasks off the web servers so that they can be focused on efficient content delivery. An ADC is a core component of an Application Delivery Network (ADN). The ADN comprises a suite of technologies that are deployed in concert to deliver applications over the network.
Content Delivery Network (CDN) – A CDN is a widely distributed collection of servers, network infrastructure and security services that are designed to deliver content to end users. This can be web sites, media files, databases or any other digital content that can be consumed. CDN’s are related to ADN’s. They are geographically spread to ensure global access to mirrored content across data centres. Load balancing infrastructure plays a vital part in allocating requests to the best CDN resources in real time.
Cisco Application Control Engine (ACE) – Cisco’s former software based load balancing and application delivery solution. It was deployed as an additional add-on for Cisco Catalyst networking switches and high-end routers. Development of ACE has been discontinued. The product is no longer available for sale, and support for existing deployments will end in four years.
Microsoft ForeFront Threat Management Gateway (TMG) – Like Cisco ACE, TMG is another discontinued network solution. TMG was a software security suite of tools that used Microsoft Windows Server as a deployment platform. It was comprised of modules to allow a Windows Server to be a router, a Firewall, and a web content cache. Microsoft announced in late 2012 that there would be no further releases of TMG.
Windows Network Load Balancing (NLB) – NLB is an optional component of Windows Server. It load balances network traffic sent to a cluster of multiple servers. NLB implements a redundant model for load balancing. If the primary server in the cluster goes offline then a secondary replaces it. As such, it is primarily a resilience solution and not a modern load balancing solution whereas the KEMP LoadMaster delivers efficient resource use and load balancing, without having servers sitting idle.
Hybrid Cloud – This term can be used for two types of (often overlapping) cloud based computing models. In the first sense, it is used to describe a model where server resources hosted in an organisation’s data centre are enhanced and augmented with server resources from cloud providers. A second sense is when various cloud-based resources from multiple public and private cloud service providers are used together to provide computing services. In many cases the line between these senses of the term Hybrid Cloud are blurred. Many organisations combine their own server infrastructure with various private cloud and public cloud infrastructure as their needs change.
Office 365 – This is Microsoft’s branding for a suite of online productivity services designed for business, education and individuals. The suite comprises various subscription based tiers that provide access to email via Microsoft Exchange Online, real-time collaboration via Lync Online, documentation management and team sites via SharePoint Online, built-in security, easy management and cross platform access to the Office productivity applications on desktop and mobile devices. Since the solutions and data are cloud based, Office 365 allows for anytime, anywhere productivity. As is business continuity as Microsoft also ensures business continuity by making sure your data and applications are always available.
