Recently “the cloud” has become a vital part of technology, and Cloud Engineering jobs have been brought to the limelight. Cloud technologies have greatly influenced how we interact with computers both for work and play. The good news is, you don’t have to have a degree in computer science to understand the Cloud. In this article, you will learn about Cloud Engineering and why this part of tech has become very important in how we think about innovation today.
Before cloud computing, there was client/server computing, a centralized location where all software, data, and control lived on the server side.
If a user wanted data or any other form of access, they could connect to the server, get access, and do work. Later, distributed computers came into existence. In this model, all computers are connected through a network. This set the footprints for the implementation of cloud computing, which came later.
In a speech at MIT around 1961, John McCarthy proposed that computers could be sold as utilities like electricity. It was a fantastic idea, but like all awesome ideas, it was ahead of its time. Because despite the interest, the technology was not ready for it in the coming decades.
Decades later, companies like Salesforce, Amazon and Microsoft implemented cloud computing technologies and other organizations followed suit.
A lot of people say the Cloud is someone else’s computer, but in my opinion, this definition should include a lot more. So what does “the cloud” really mean?
The cloud is a collection of computing resources — databases, servers, storage, applications, networking capabilities, and more — hosted at a distant data center and operated by a cloud services provider. The provider makes these resources available for a subscription fee or via a pay for usage model.
Now that you know what the cloud means, the concept of Cloud Engineering should make more practical sense. Cloud Engineering is engineering in the context of the cloud. It leverages the methods and tools of engineering in designing, building, operating and maintaining cloud services. Often, Cloud Architects, Cloud Engineers, and/or Solutions Architects are in charge of connecting complex business problems with the proper cloud solutions through solution architecture and design.
In recent times, many organizations have embraced and hired for more Cloud Engineering roles. This is because of the importance of the cloud in technology and innovation in general. Cloud Engineering helps organizations achieve the following:
Infrastructure as a Service (IaaS) is a self-service model for managing infrastructure in data centers. Organizations pay for IaaS on a subscription as opposed to buying physical hardware. This model enables companies to add, delete, or reconfigure IT infrastructure on-demand.
Platform as a Service (PaaS) makes it more straightforward and quicker to develop, test, and deploy applications.
Developers can focus on writing code and building applications without worrying about time-consuming infrastructure activities like provisioning servers, storage, and backup.
Software as a service (SaaS) substitutes the traditional on-device applications with applications hosted in the cloud. SaaS applications can be accessed directly from a web browser and they don't require any downloads or installations.
Cloud service models exist beyond IaaS, PaaS and SaaS. There are other ways that computing services are provided on the cloud and some of them are listed below:
In this article, we will touch on Database as a Service.
Database as a Service (DBaaS) is a cloud service model that allows users to access a database system on the cloud without buying and setting up their hardware, installing their database software, or managing the database themselves. The cloud provider handles periodic upgrades, backups, availability and security.
HarperDB has a cloud offering that could be considered a DBaaS, PaaS, or SaaS. It handles the deployment and management of your instances in just a few clicks. Currently you can spin up either an AWS (Amazon Web Services) instance or a Verizon Wavelength instance through the HarperDB Studio:
HarperDB can run on anything with an operating system, and saves valuable resources by removing the need to set up and manage database systems and the IT environment. Other advantages of HarperDB Cloud are listed below:
In this article, you learned about Cloud Engineering and its importance in our industry today. You were also introduced to traditional cloud service models and some new cloud models, including Database as a Service (DBaaS).
