Title: Know how serverless java is possible?


1
What Server less Java Means for Developers
2
INFORMATION
  • Server less doesnt mean there are no servers.
    Its the first misnomer that should be explained
    when looking at this technology. 
  • Server less simply means its not your server.
  • As far as youre concerned, its server less
    because someone else owns and manages the server.
  • That someone else takes care of setup,
    infrastructure, scaling, and anything else
    connected to the servers.
  • Theres no special language associated with
    server less either.
  • If another language is more familiar, most
    providers let you use whichever programming
    language you prefer.

  • Also known as a function of a service or FaaS,
    server less gets this alternate name because of
    where you do the work.
  • If you think of an application being generated in
    layers, starting with the very root of the
    infrastructure, then FaaS is just the very top
    layer.
  • Everything below the application layer is part of
    the infrastructure, and is handled by someone
    else. Youre only creating at the top.
  • The impact of server less for developers is
    highly beneficial.
  • By eliminating the more time-consuming part of
    their job, managing servers, theyre freed up to
    work on creating the final product.

SHIFTING FOCUS 
  • When a developer doesnt have to worry about the
    basic setup of a system, they have more time to
    devote to other areas of their project.
  • When the underlying infrastructure has gone
    server less, and someone else is handling that
    aspect of a project, a developer can focus more
    on the code necessary to complete the
    application. 
  • All you have to do, as a developer, is write the
    functions and applications that use those
    functions. 
  • This extra time to focus on the end product then
    leads to a shorter development time.

5
IMPROVING ACCESS
  • Once youre ready to deploy, server less systems
    give you immediate scalability.
  • If one day you have five users, but the next day
    you launch to thousands, you wont have to worry
    about whether or not the underlying
    infrastructure can handle the jump. It can.

6
MOVING FASTER 
  • With the ability to complete projects faster
    since maintaining the infrastructure is no longer
    taking up the developers time, a ripple effect
    occurs.
  • Faster development and faster testing enables
    faster innovations to take place.
  • New iterations of your initial application can
    get completed and released faster as well,
    allowing you to provide users with a superior
    product thats always at the forefront of new
    developments.
  • New ideas can get tested on a much faster
    schedule as well since each idea no longer needs
    its own server set up first.
  • The infrastructure for testing is already there
    and waiting for you to use immediately.

7
CUTTING COSTS 
  • When you own the server your application runs on,
    youre paying for that web server regardless of
    whether or not your applications are active.
  • If no requests are coming in to engage with your
    application, youre still footing the bill.
  • This can end up being a costly prospect,
    especially when compared to the number of users.
  • A low level of engagement can bring down the
    return on your investment (ROI.) Running your
    application server less, you only pay when the
    code actually runs.

8
  • This can greatly reduce operating costs because
    you no longer need to spend the money on the
    server itself or the n people managing the
    server.
  • Instead, personnel will manage a cloud
    environment, which is a much easier job.

WORKING WITH JAVA IN A SERVERLESS ENVIRONMENT 
  • For Java developers, there may be a little
    hesitation when it comes to working in a server
    less environment. 
  • Firstly, Java Functions can start a little slow
    and take up a lot of memory.
  • The time impact to load is usually not more than
    a few seconds, but that can matter in a highly
    competitive situation. 
  • Technology like GraalVM, for example, addresses
    these Java-based pain points to help code run
    faster.
  • It compiles Java byte code to native images. Used
    ahead of time  of compilation, the dependency
    graph is built before starting the JVM so start
    up happens faster.
  • With a smaller size and a faster load time, the
    issues with Java wont feel be as impactful for
    code selection when working in a server less
    environment.

WEIGHING THE POSITIVES
  • As a developer nothing is more valuable than
    time.
  • Working in technology, many applications being
    developed are on a tight schedule to go out
    before the competition. 
  • Theres also pressure to say at the top of the
    game operationally, constantly testing and
    updating to release improved versions to optimize
    user experience.
  • One of the best strategies to ensure developers
    have enough time to accomplish all of this is to
    eliminate any drags on their workday. 
  • By passing on the management of the server and
    all functions that go with it, to go serverless,
    developers can hone in on coding and running
    applications that make impact.
