Because even in the clouds there is lightning

There have been quite a few people recently scattered on social media with an article blog Personally about the disappointment of a startup founder from Yogyakarta due to the failure of the service provider cloud server trust, causing business data (on website servers and email servers) to simply disappear. This suddenly makes many parties become worried, from the beginning felt safe and comfortable putting their products and services on brandcloud server famous, is now starting to be haunted by the same issue. It is important for us to try to redo what the concept really is cloud computing it works.

Cloud computing or cloud computing start hyping since the beginning of the millennium. His presence started by the rapid use of VPN (Virtual Private Network) among internet users – if the network can be made private path with ownership that is simpler and cheaper, what about the server – Amazon became a key player in the early presence of cloud computing services. The popularity of these services is increasingly promising when brand Big companies such as Microsoft, Google and IBM also enliven the market with a variety of services and guarantees for user convenience. Cloud computing products began to narrow to reach consumers, from the form of SaaS (Software as a Service), IaaS (Infrastructure as a Service), and PaaS (Platform as a Service).

The purpose of the cloud computing concept is getting clearer, which is to make developers focuses on the product, not on infrastructure management, in this case the server. Server systems have become a dominant role as businesses are increasingly dependent on the online world. The rapid growth of traction and product dynamics are key considerations. As a result, cloud computing services are selling well in the market. The fact is so too. Cloud computing services really simplify the process of managing and maintaining server infrastructure. Interestingly, this service also provides flexibility and scalability in use, as well as the payment system. “Pay as you use”.

Cloud computing is still supported by physical servers

The Jargon Service Level Agreement (SLA) is one of the fastest being offered in the marketing of cloud computing services. The percentage of 99,99% SLA is often proffered to convince users to put their application system to the service. It is known but often ignored that when we talk about cloud computing we are actually talking about physical servers, it's just that we rarely know about their location. The concept of virtualization is one that plays a major role in cloud computing civilization. System mirroring or server duplication too.

The difference between providing a server on-premise (manage data center independently) by relying on cloud computing services is in the range of management and maintenance. While the similarities, both rely on the "credibility" of the server computer. When we manage the server directly on-premise then the full care is in our hands, plus management. The difference is when subscribing to cloud computing services, we entrust the care to other parties.

So the red thread can be drawn. It's just a matter of server location and maintenance. Its form is still a server computer, not a super power floating in the atmosphere. This means that 0,01% outside the SLA could tell us that the server computer caught fire or exploded.

The boring activity calledbackup

Realizing that cloud computing is still a physical form of server computers, concerns seem to need to be reinvested. Questions like “What if suddenly the SSD (Solid State Drive) on the server crashes corrupt?”, “What if there is damage to the CPU on the server?”, and so on are important to consider, at least to burn laziness to do a boring activity called “mem-backupdata. Unfortunately until now there is no brand who can actually provide 100% SLA covering the entire service cloud server being peddled.

If the much-lauded class of Digital Ocean can't restore the lost Fitinline data on its server, then the task is backup be on the agenda that should be crucial. It could be that a large online business needs to allocate a special team tasked with doing this backup data. It's like an insurance. If there is no accident, it will only appear as an activity that wastes resources. However, if you remember that a physical object can be affected by bad risks at any time, then it should be prepared more carefully.

What to expect from a cloud computing service?

In addition to cutting down the complexity of managing server resources, the use of cloud computing is often associated with tiered needs, especially for startups. Generally, startup starts with a minimal capacity system so that it does not require large resources. As users of a service grow, sometimes startups need to make improvements (upgrades) server system quickly, compensate for the surge encountered. Cloud computing facilitates these needs well, because one of the visions to be pushed is easy scalability.

Access speed is also a consideration when someone entrusts putting a system built on a cloud computing service. Generally cloud computing service providers offer convenience of choice data center in accordance with the target use, the goal is for faster access. Currently being peddled for a service – for example a website – is not just a system hosting, but leads to a VPS (Virtual Private Server) or VM (Virtual Machine). What is rented is not an empty space with a certain capacity, but a single server system.

One of the other crucial things is related to the guarantee of the data uploaded to the server. It is necessary to fully understand the terms of the SLA and the limitations of the responsibility of the cloud computing service provider before choosing, so that from the usage side we can determine the actions that need to be taken to disaster recovery when a failure occurs on the provider side.

Technology is now the key to a growing digital business and will continue to be a dependency. Readiness to face various possibilities is also crucial, because in the clouds there is also lightning that can strike at any time.
