Serverless Computing: Revolutionary innovation in IT universe



Spurt of innovations in IT arena enables companies to perform their operations smoothly and gain competitive advantages.  The prime application of Serverless Computing is to enable businesses agility, increase resiliency and drive cost efficiencies. Major breakthrough in technical enhancement is the server computing which allowed enterprise IT to develop and deploy scalable software without concerned about the fundamental infrastructure.



In Serverless Computing, servers are an main fragment though, it is the cloud provider which deals with the intricacy of managing individual servers and provides temporary compute service, that will execute a piece of code on-demand generated through requests and events, with the service customer being charged only for the duration of implementation. To put in simple way, Serverless computing add a layer of abstraction on the top of cloud infrastructure, therefore, developers do not concern about provisioning and managing physical or virtual servers in the cloud. Serverless computing gives software developer the capability to develop, deploy and run applications without management of servers.



Developing Serverless computing applications, professionals focus on solving the core business problems instead of spending time on how to operate and manage runtimes or compute infrastructure, either in the premises  or in the cloud. Key objective of Serverless computing movement is to offer high level abstraction of the computer infrastructure so that developers can concentrate on resolving  critical business issues, deploy them instantly and reduce the time it takes for business ideas  to be marketed.



Serverless computing is a fruition of cloud computing service models–from Infrastructure-as-a-Service (IaaS) to Platform-as-a-Service (PaaS) to Function-as-a-Service (FaaS).



Merits of serverless computing are reduced operational cost, rapid development, scaling cost and easier operation management. There are some restrains of serverless computing to implement serverless applications such as infrastructure control, long running applications, vendor lock in, cold start, shared infrastructure and limited number of testing tools.



Wrapping up technical wires, serverless computing is an impressive innovation in II.it is event driven FaaS technology that uses third party technology and servers to eliminate business issues and maintain infrastructure to create an application. It may be the solution of new architecture that is going to be built. It has numerous upsides like operational efficiencies and easy management but it is not free shortcomings. It has less testing tools, vendor lock in and many. In nutshell, serverless computing is a novel cloud computing prototype with mammoth economic growth potential.

Quiet quitting: Professional roadblock or mental strengthening

The workplace scene is drastically transformed with the inception of digital technology. Executives and professionals are constantly adapting to a novel work environment. In today’s modern work atmosphere, quiet quitting is rapidly growing among professionals to maintain work life balance. Quiet quitting is gaining impetus due to the nature of professional tasks in business companies is hectic, monetary centric, highly burdened. Presently, personnel are more particular and conscious about their comfortable living. They just finish their assigned job in office hours and do not want to put extra effort to augment the brand of the company.   Quiet quitting is not about resigning from a post.

Technology outage is a calamitous impact on various services and disrupts or halts the operations of airlines, medical services, media channels, banking services, railways and business operations all over the world as these are connected with computers. Recently, a giant tech Microsoft system server crashed suddenly, causing a major breakdown in the server network which led to errors in the login system, airlines operations and others that paralyzed most parts of the globe. The issue erupted in the process of updating some security software which led to an outage of the server and thus stopped all user services globally. The problem affecting the majority of services was caused by a flawed update by CrowdStrike, an American cybersecurity firm responsible for offering protection to existing users from any cyber threat.   Network outages may be due to a gamut of technical reasons which have the power to crash the computer services and interrupt connectivity. Such a network crisis has
