A recent study claimed that cloud computing will create more jobs than the early Internet boom did. The industry is slated to create big business opportunities, as well as hundreds of thousands of jobs. In fact it is such a big deal, venture capitalists are expected invest upwards of $30 billion into the industry over the next five years or so.
Cloud Education is a Top Priority
Fortunately, you won’t have to wait five years to see the effects the industry has on the job market. Currently, there are far more of these employment opportunities than qualified candidates to fill those positions. Jobs are being advertised ad nauseam across the Internet and even Rackspace, a huge name in the cloud computing industry, is looking for new talent. These jobs are expected grow dramatically over the next few years. According to a report by technology analyst firm IDC, available cloud-computing jobs are expected to reach 14 million globally by
2014. While this is a good problem to have, it is a problem nonetheless. The industry needs a large stable of qualified IT
managers, systems administrators and network engineers to meet the rapidly growing needs of this technology.
Cloud Computing 101: Introducing CloudU
Part of the problem is that while there is plenty of discussion about how awesome it is, there is not much discussion about why it’s awesome, and how it works. Rackspace has built an intensive online resource, providing educational tools to train the general public, and potential Rackers (read: employees) in cloud computing
concepts. The resource is called CloudU, and answers two big questions right off the bat within the first couple of lessons:
1) What is cloud computing? & 2) How do I understand the cloud computing stack (Iaas, PaaS, SaaS)?
• What is Cloud Computing?
In previous years, enterprise-level computing was expensive. It was expensive on two levels: On one level, storing and managing massive datasets required massive processing power, which is definitely pricey to maintain. On another level, running in-house server technology and data centers required using lots of electrical power. It provides high-powered processing, while keeping electricity consumption low, and at a fraction of what it would cost to run a dedicated server or data center for a large-scale company. This is all accomplished in cloud-based data centers where processing and hardware resources are shared among multiple servers simultaneously. This gives the service providers the ability to provide scalable, customized computing resources on a subscription or as-needed basis to their customers.
• Understanding the Cloud Stack
The cloud stack is broken into three distinct components:
Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS).
• IaaS – Infrastructure-as-a-Service providers, sometimes called Hardware-as-a-Service (HaaS), is just that, a provider of server hardware for companies. Companies can rent server space, hardware and operating systems, and have them installed on-site or at a third-party location. Rackspace is among the largest providers of IaaS solutions.
• PaaS – PaaS is often referred to as middle-ware. This is because PaaS solutions provide an easy path of all a company’s application deployment needs. This includes server space, operating systems, and a host of deployment methods that cut the app development time in half.
• SaaS – SaaS is the most common type of service, primarily because it is the easiest to access and use. Essentially, SaaS providers offer powerful software solutions over the web. This includes everything from storage to word processing to digital video editing. SaaS includes any type of software that you can use online.
Everyday, technology is becoming more of an omniscient presence blanketing the planet. As these types of networks continue to augment traditional server delivery and mobile technology expands to necessitate more cloud infrastructure, we can expect jobs in the field to continue blossoming long into the future, potentially growing to make cloud computing and information technology one of the foremost industries in the future.
