Often times, websites get inundated with traffic which when poorly managed will result in dissatisfied customers, loss of revenue, or even a website crash! Especially, festival or holiday seasons bring with them these daunting scenarios as free offers! Not any company will have the IT team fully triggered to cater to the sudden surge in traffic or piggyback additional servers instantly! What comes in handy at such challenging conditions is Cloud Computing.
What is Cloud Computing?
If ‘Cloud Computing’ sounds Greek and Latin to you, here is what it is. It is an internet-based computing that allows sharing data, information and resources across computers and other devices on-demand. Users or firms get access to store and process data in third-party centers.
One of the major reasons to prefer cloud computing is its ability to cope with high traffic sites which is rather not possible with dedicated servers. Although it is possible to gather power by integrating the dedicated servers, this, in most cases is time consuming and a tiresome job requiring continual attention by employees to put the server in the rack.
Eliminating these hassles, cloud enables calling upon virtual machines and resources in a jiffy. While a dedicated server demands complete installation of OS right from the scratch, it is enough if we use a pre-developed template to create cloud virtual machine. This largely cuts down on the time consumption.
A cloud virtual machine can be configured for load balancing in more or less the same way practiced to develop a load balancing cluster. In load balancing, one load takes position as the load balancer. This stands responsible of distributing the traffic among all the other servers in the cluster, thus reducing the burden on a single load. The load balancing concept is ideal because this can be integrated with the cluster to manage the load without bothering the other servers functioning in the environment. There are multitudinous cloud platforms that serve customers in creating virtualized load balanced clusters. They enable customers to virtualize their physical infrastructure in use.
Auto-scaling is offered by various cloud platforms such as eNlight. Auto-scaling lets your virtual machine obtain add-on resources from the cloud and eases dealing with extra traffic during peak hours. You perhaps have already got specific level of resources installed and functioning in the dedicated server. Those with the cloud virtual machine are flexible that it meets your demand, serving the need.
Here, there is not much need for spending money as the only need is towards the actual resource consumption and not for the add-on resources; these get eliminated from being accounted for the commercials as they will be absorbed back into cloud once they are done with their job. Autoscaling is also beneficial in staying safe from getting fleeced by large bills to customers. This is achieved by limiting the money spent.
The way in which you make use of cloud for managing high traffic sites is totally dependent on the individual requirement. For requirements demanding a long term solution, the ideal way is to choose cloud load balancing configuration as it allows addition of nodes over time so that there can be a decent performance served to the traffic received by the website. On the other hand, in case of short term issues requiring a solution for time being, the ideal choice is Auto-scaling. For example, Auto-scaling is recommended for cases such as load spikes.
When auto-scaling is practiced long period, it would cost you high. For requirements demanding permanent or long-term solution, the best choice is to upgrade the base resource of virtual machine or prefer load balanced configuration.
Every time a visitor clicks on to your website, he or she gets redirected to your web server which is present at a central location. So each of the visitor hitting your site will hold access to your web server. When your website absorbs huge traffic with its excellent navigation and quality content, it results in overloading of the server and it in turn leads to heavy traffic on to your site. Here is when CDN steps in. CDN is stands for Content Delivery Network. These are networks of servers that are wide-spread across the globe. All the static content present in your web page gets stored here. This includes java scripts, images, flash, and so on. CDN manages the traffic by redirecting them to the closest server.
Hope this help you. See you in my next post.
