Essential primer<\/strong><\/span><\/h2>\n\n\n\n

When you use an electrical appliance, you use switches to manually change between the ON and OFF usage states. You are billed only for the duration you use those appliances, not when they are in the OFF state.<\/p>\n\n\n\n

Correct?<\/p>\n\n\n\n

By switching ON and OFF you\u2019re triggering events. Similarly, applications running on the cloud, can also have an event driven software architecture with ON and OFF states. Such applications are programmed in a way that each feature can be accessed or turned ON or OFF, based on when a user needs to access that feature. Features are treated as services, and are only invoked in response to certain user events; you\u2019re billed only for the time those functions or software components are alive.<\/p>\n\n\n\n

If your app has N features, and each feature can independently offer itself as a service, turn ON when the user needs it and turn OFF when the user doesn\u2019t need it, then your app is well aligned with the \u201cServerless Architecture\u201d, actively practicing the idea of \u201cMicroservices\u201d.<\/p>\n\n\n\n

How does it simplify your developers\u2019 roles? They no longer need to worry about physical hardware, virtual machine operating systems and web server software management. They just need to code functions.<\/p>\n\n\n\n

\u201cThere\u2019s no servers to manage or provision at all. This includes nothing that would be bare metal, nothing that\u2019s virtual, nothing that\u2019s a container\u200a\u2014\u200aanything that involves you managing a host, patching a host, or dealing with anything on an operating system level, is not something you should have to do in the serverless world.\u201d<\/p>\n\n\n\n

Bottom line: Build more, manage less<\/em><\/strong><\/span><\/h3>\n\n\n\n

Software developers can focus entirely on writing highly efficient and scalable object oriented code in smaller deployable units that perform core specific functions. Developers need to be concerned only about writing core business logic of the application and simply not worry about code integration and delivery.<\/p>\n\n\n\n

Now, what\u2019s becoming extinct?<\/strong><\/span><\/h2>\n\n\n\n

Gone are the days when IT run businesses had large air conditioned server rooms, with tight security and restricted access. Businesses then had to invest in purchasing server infrastructure, own a server completely to run their applications on it, establish a dedicated server room and a DevOps team to monitor server availability and security.<\/p>\n\n\n\n

This was also because Businesses assumed a pressure to be alive every moment, instead of being \u201cdemand-driven\u201d or user-event driven.<\/p>\n\n\n\n

Age of fractional ownership<\/strong><\/span><\/h2>\n\n\n\n

Amazon and Google today are offering \u201cvirtual, fractional ownership<\/strong>\u201d of cloud server infrastructure, in other words\u200a\u2014\u200aability to rent out server infrastructure, so you pay only for the time you\u2019re running your business on cloud (instead of buying the server). Your server availability is proactively managed by your cloud provider along with proactively upgrading it\u2019s configurations based on application usage.<\/p>\n\n\n\n

This relieves businesses from spending time and money on DevOps and enables them to focus more on programming features.<\/p>\n\n\n\n

What\u2019s exciting about this?<\/strong><\/span><\/h2>\n\n\n\n
\n

Serverless computing pushes your business to become a more assertive, \u201cdemand-driven\u201d business, than a \u201csupply-driven\u201d business.<\/strong><\/p>\n<\/blockquote>\n\n\n\n

You could run every feature of your product or service, as an independent service that\u2019s available online for a select few hours, only when it\u2019s needed.<\/p>\n\n\n\n

Serverless Architecture allows coding a Function as a Service (FaaS), <\/strong>also called a Microservice<\/strong> which is making life a lot easier for businesses today, as all you need to do is now code each feature as a Microservice (which the server understands how best to run it), without having to worry about server availability, active server monitoring, management and maintenance.<\/p>\n\n\n\n

Greater business agility<\/strong><\/span><\/h2>\n\n\n\n

Lesser Deployment Time (Time to Market)<\/strong>\u200a\u2014\u200athe time required for Packaging and deploying a new functionality or FaaS application is significantly less compared to regular self-managed server approach; as serverless obsoletes a lot of tasks (like managing and running core services such as databases and load balancers) in the deployment process by proactively taking care of it.<\/p>\n\n\n\n

Faster Response to Market Demands\u200a<\/strong>\u2014\u200aBusinesses can be swift in responding to ever changing market conditions and demand as developers can just tweak the existing code a bit or write some new functionality (if required) and deploy it just with a few API calls without worrying about code integration and delivery i.e., in serverless architecture scalability is possible at function level, unlike other virtualization mechanisms where scalability is only possible at application level.<\/p>\n\n\n\n

It\u2019s now extremely simple for software engineers to develop, deploy and manage applications running on the cloud. What once costed thousands of dollars to run your app on a cloud server now has dropped down to more than 1\/10th the original cost, due to this \u201cvirtual, fractional ownership<\/strong>\u201d concept, with an all new \u201cserverless<\/strong>\u201d way of coding your app and simply renting out a server to run it.<\/p>\n\n\n\n

Many more reasons to love<\/strong><\/span><\/h2>\n\n\n\n
    \n
  1. AUTO-SCALING: What if someone else took care of automatically scaling up or scaling down your server configuration & availability, based on how many people are using your application in realtime? Amazon Lambda, Google Firebase and IBM OpenWhisk intelligently create more and more copies of your features \/ functions (Microservices) that can be available as services to more and more people as the demand rises. You can customize this auto-scaling behavior by writing your own custom cloud functions!<\/li>\n\n\n\n
  2. AUTO-HOSTING: All aspects of hosting your application is taken care by your cloud vendor (like Firebase, Lambda or Azure). Developers need not write any server hosting functionalities as vendors already are providing commonly used server functionalities<\/strong>. Developers can simply invoke these standard functions by making API calls. Also, reg. Security<\/strong>\u200a\u2014\u200ait is much simpler for developers to implement security practices and protocols, as directed by the serverless environment.<\/li>\n\n\n\n
  3. EVENT-DRIVEN: Serverless architecture, fundamentally pushes your business to be demand-driven or event-driven, turning ON \/ OFF in response to a user event. This questions businesses that are blindly available 24\/7 online, even when there\u2019s no demand. Sometimes\u200a\u2014\u200aLess is More. Reiterating the cost savings\u200a\u2014\u200awith serverless, your business saves about 60% of your cloud infrastructure costs as you don\u2019t have to pay for server downtime or idle time. In serverless, you are billed only when the memory space reserved for your functions that are in active use (running state) and some amount for the resources it requires to run.<\/li>\n<\/ol>\n\n\n\n
