We are all speaking about it, businesses are embracing it, but what is it?
Cloud computing in a nutshell is when you use a network of remote servers to store, manage, and process data, rather than a local server or your own PC. It all sounds very simple but the world of cloud has many branches to consider often making it hard to see the wood from the trees. With each leading vendor providing a range of packages and solutions, putting your finger on what cloud technology is and how it affects you from anyone’s perspective: consumer, business owner or candidate is a difficult task.
Thus, the champion of the cloud is yet to be crowned, per the likes of Brian (director of enterprise architecture at cloud management provider RightScale) it is a three-horse race but far too close to call. The three market leaders in this space; Amazon Web Services, Microsoft Azure and Google Cloud platform all have various storage options and packages based on the consumer needs. Brian outlines in his recent webinar that “[Is anyone in the lead?] It really depends on what you’re using the cloud for”. Each provider has their own strengths and weaknesses depending on the specific use he says.
In this blog, I am going to outline the different types of cloud deployment before exploring what all the hype is about and the consequent effect for candidates in the job market.
Types of deployment
There are three types of deployment when it comes to the cloud Public, Private and Hybrid.
Public clouds are owned and operated by third-party cloud service providers all hardware, software and other supporting infrastructure are owned and managed by the cloud provider E.g. Microsoft Azure. You access these services and manage your account using a web browser.
Private cloud is infrastructure solely in operation for a single organisation this infrastructure is maintained on a private network. This cloud infrastructure can either be located in the data centre of the company or can be hosted by a third-party vendor.
The best of both worlds: the hybrid cloud is what it says on the tin it combines both the public and private cloud. The hybrid cloud uses the private cloud as a foundation to use the public cloud services allowing applications to be shared between them. Quite often companies with private cloud infrastructure will evolved into a hybrid cloud environment to manage workloads across data centres, private clouds, and public clouds. This allows them to be dynamic but keep the critical applications and sensitive data in a traditional data centre environment or private cloud.
Why is the cloud so sexy to businesses then?
Cloud benefits a company’s outgoings twofold. Firstly, companies are saving money without the overheads of physical infrastructure. But not only that, they are also getting well on the way to going green without the expense of round the clock electricity for power and cooling. Secondly, it increases cost predictability companies can buy what they need without having to predict what capacity and functionality they will need in the next 3-5 years
Most cloud computing services are provided as self service and on demand, so even vast amounts of computing resources can be provisioned in minutes, typically with just a few mouse clicks, giving businesses a lot of flexibility and taking the pressure off capacity planning. On-site data centres typically require a lot of “racking and stacking” – hardware setup, software patching and other time-consuming IT management chores. Cloud computing removes the need for many of these tasks, so IT teams can spend time on achieving more important business goals.
If there is a disruption to the network cloud providers can provide disaster recovery, this avoids time consuming and disruptive in-house fixes. Also, data stored in the cloud can be mirrored at many redundant sites making data back up and disaster recovery less of a disaster.
Cloud computing enables smaller businesses and start-ups to grow faster without the restriction of physical hardware costs. These smaller companies can keep up with the larger corporations on a technology front. In addition, cloud computing facilitates invaluable collaboration, the ability to share files and data quickly and safely increases workflow and productivity. The step for a company to go global is bridged by the cloud.
Nothing holding the IT department back now, the cloud providers take on all the upgrade and maintenance responsibilities for the cloud leaving the IT department to focus on pushing their company forward onto cutting edge technologies increasing the reliability and speed of their functions.
What does this all mean for the candidate
Needless to say, more and more companies are taking advantage of the benefits cloud can offer their business. Thus, we are seeing a wave of cloud migrations occurring across our client base. This is a huge opportunity for individuals to improve their skillset by getting exposed to cutting edge technology. The job market is getting broader and more diverse meaning that engineers must become more dynamic and proactive in their pursuit of a successful career. With companies introducing new technology in their environment there will be increased movement of individuals from company to company. In order to end up on the right side of this wave ensuring a long and successful career both recruiter and candidate must embrace this change. From a candidate point of view be proactive, what’s your current company’s plan regarding a migration to cloud? Are you part of it? Are there companies that you have always wanted to work for now hiring?
Our job as recruiters is to help you answer some of those questions and work out what is the best next step for every individual during this exciting time.
