What serverless computing is and should become

Computer Essentials: Article Critique


Cloud computing can be defined as delivering computing services over the internet. This article tries to expound more on serverless computing, the second phase of cloud computing. The first phase majorly focused on cloud system administration which made it easier to manage and configure infrastructure with the help of networks and virtual servers. The main objective of the study carried out by Schleier-Smith, and his colleagues were to simplify the second phase of cloud computing by hiding the serves and providing obstructions to application builders, thus making cloud software easier to write. The new phase of cloud computing is known as serverless computing, and it comprises much more than cloud functions (Schleier-Smith et al., 2021). Today, serverless computing functions well with limited applications and enables cloud providers to create general-purpose serverless products that allow more use cases.

According to Schleier-Smith et al. (2021), serverless computing has enabled programmers to create applications with the help of high-level obstructions provided in the cloud. The article has provided three critical qualities of serverless computing: providing an abstraction that inhibits the servers and programming complexity and offering a pay-as-you-go model that eliminates charges for idle resources. It provides rapid, automated and unlimited scaling resources that closely match the demand. This quality offers alternative sets that might be taken together to meet an ever-growing demand (Schleier-Smith et al., 2021). The article further reveals that cloud computing has shaped some business considerations. Many businesses have chosen serverless computing as it permits them to stay engaged in solving unique problems in their industry or domain. This article suggests two essential areas that may enhance cloud computing functions and enable serverless computing to work with a broader range of applications (Schleier-Smith et al., 2021). First, the authors suggest that hints provided by the programmer might assist in achieving better performance. These hints can be used to describe patterns of application communication as well as present affinity task placement. Another suggestion offered by this article is removing envision inefficiencies by automatic optimization.

Some of the challenges offered by this article in serverless computing include state management, whereby cloud applications may require to exchange ephemeral state or short-lived component tasks. Another challenge is networking, which occurs due to the tension created when giving programmers more control and allowing cloud providers to auto-generate optimization. Other highlighted challenges include predicting performance, security, programming languages, hardware and machine learning. This article concludes by revealing how serverless computing has evolved and flourished within a decade. It has offered lower costs and simplified business administration, enabling the business to grow. Besides, the article has provided some predictions that may occur in cloud computing over the next ten years.

The article has revealed the expectations of serverless computing, which act as the second phase of cloud computing. I agree that it has provided a simplified operating model attained by hiding servers. In my own opinion, I believe that the future of cloud computing will be channelled by enhancing efforts that aim at simplifying cloud programming. I agree with the article that serverless computing entirely remains the application-specific variety. With application-specific serverless, cloud computing providers offer BaaS proliferation that meets the need and demand of ever-growing applications. 

Today, we tend to use cloud computing every day without even noticing. Cloud computing is well different from others due to how it is managed. For instance, we don’t have to worry about purchasing licenses for word-processing software or keeping them updated during web browsing. Web browsers facilitators such as Google does all that, therefore we don’t need to worry about how the service we are buying is being provided. According to Schleier-Smith et al. (2021), Web-based services have enabled us to concentrate on our jobs without worrying about who is providing cloud computing services. Cloud computing has also affected how we use our emails, software and hardware application. Through the help of the internet, we can now send email messages and reach their destined recipients within seconds. These emails may include other attachments such as formatted documents and images as attached files. Besides, through the help of the internet and intranets, cloud vendors today can create virtual servers on software and hardware platforms. In this case, cloud vendors can quickly scale up or down and housing many clients on a single piece of server hardware. Lastly, cloud computing has also impacted how we work with Microsoft office. When we sign in on any device and launch one of the Office apps, the new Start screen shows you right away that you are in your Office. In this case, MS Office can reveal the list of documents that I have accessed using my computer or any other connected device.
