End User Driven Technology
Over the last decade or so, with the phenomenal increase in network sizes and also that of the users on the same, there are frequent latency delays, which end up frustrating end users. At the end of the spectrum, it's these user issues which matter far more than internal frustrations and guaranteed availability is not just about alleviating the managed services, it's also all about extending a seamless experience. Infrastructure growth is explosive and over provisioning is no longer tenable or manageable given the costs of purchase as well as maintenance. We need a smarter solution and we need it now !
If the execution of an application is not experiencing resource constraints at the application server, database server or at the network connectivity levels, the assumption is that the specific business service(s) must be performing well or at least that’s what the first cut impression comes out to be. But as far as the service provider is concerned, the business is not performing well whenever it does not work as expected or against targeted expectations from an end user's perspective. Hence, between IT and the business, there’s a gap which clearly exists and which can be seen and captured in customer experience matrices. These issues are quite serious in nature and cannot be tackled and eradicated by mere production of reports. So, what's the next step ?
It now becomes highly imperative to optimise existing elements of the IT environment. It now is the demand of the hour to perceive the behaviour of computing and data traffic to ensure sustainable capacity in order to deliver a steady end healthy end user experience.
A Suggested Solution : Abstraction
Nowadays, hardware specific products have become an irrelevant commodity. The cost of hardware is only sustained by included software mostly proprietaries, which can create ‘islands’ of incompatible products, each with their own licensing costs. A decade ago, Java showed the value of abstracting an application from an operating system. This concept of Java abstraction later found its way into hardware through the hypervisor, which abstracts the operating system from the underlying hardware.
This new value proposition and focus is clearly evident in the virtualisation and which in turn further extends to converged infrastructure and hyper-convergence. The virtualisation and convergence break down the siloed components, such as facilities, servers, storage, networking and integrate all of these into existing infrastructure to optimise enterprise level IT solutioning. Virtualization can be viewed as part of an overall trend in enterprise IT that enables computing to be self-reliant, in which computer processing power abstracts from computer hardware and is managed centrally, it also helps to achieve the flexibility in scalability and workload management thereby creating a very enhanced end user experience.
The masking of server resources from server users is known as server virtualisation which can enable an increase in the shared resources and their capacity. Network resources in virtualisation can enable a multi channel split between available bandwidth, each of which can then further be assigned to particular servers independently. Storage can create a pool for physical data management from multiple network storage devices and in turn can be centrally managed.
The unified architecture is somewhat interchanged with converged infrastructure that isn’t usually a piece of networking hardware. Conversely, converged or hyper converged infrastructure usually just stores and computes and these kinds of platforms are small, powerful as well as dynamic in terms of applicable entity usage. This convergence and virtualisation allows you to integrate infrastructure with a pool of resources and abstract services underlying the physical architecture.
Managing Effective Acceleration
Networks carry huge volumes of mission-critical data, including financial, logistics, customer records, inventory and general content delivery. All of this can be brought to a crawl by traffic jams on the network. An unexpected traffic surge or temporary network interruptions can cause a marked degradation of performance. Determining optimised solutions for network path & links is imperative to ensure improved end user experience.
As bandwidth becomes more constrained, traffic re-engineering and prioritisation becomes extremely important. A strategy is very badly needed in the current times for generating ideas around acceleration required to handle and improve the efficiency of different types of content delivery and traffic flow over intra & inter-networks. An acceleration of data traffic and content delivery by the technique of WAN optimisation and content delivery network (CDN) to improve the performance of network infrastructure, further augment WAN aggregation and application delivery optimisation.
WAN acceleration also known as WAN optimisation lies in the category of technologies and the techniques that are used to maximise the efficiency of data flow across the wide area network. It achieves the optimisation to increase the speed of access to critical applications and information. Something that is very imperative, given the current scheme of things and the way network speeds are being impacted nowadays. Content delivery networks (CDNs) are interconnected networks of servers strategically placed around the globe to accelerate web content delivery, reduce load times, and improve online user experiences. CDNs also serve as a fail-safe system to ensure the site is always available during traffic peaks and server outages.
