AWS (Amazon Web Services) lambda
AWS is a platform that allows computational operations to take
place for any desired outcome. How can it help in creating blockchain app, any
idea? Well, coming back to AWS, the important feature to note is that this
platform operates without a server. Thus, it allows any user and developer to
use its services anywhere anytime. This service is provided by amazon. It
provides various features that will help the developer to build theirs or
customers desirable application as AWS provides elastic storage.
Some of it features include the ability to build an application
whose features can be operated from the back-end using API of lambda. It allows
the users to use any programming code without any restriction too, etc.
Everybody knows what blockchain is. It is a digital ledger
platform that stores, records and allows transactions to take place anytime and
anyplace. It operates on a decentralized network without any central authority.
This allows users or developers to create and provide many features such as
borderless, unrestricted access to data and transfer, transparency, etc.
Imagine the possibilities and opportunities that can be grabbed if
lambada services provided by amazon is used to build an application that work
with blockchain too. A serverless application with a decentralized network, it
gives a nice ring to all developers doesn’t it? This article discusses about blockchain app development using Lambda.
Building blockchain app on AWS Lambda
Use the computational lambda services provided by AWS as the base
tool to build a strong infrastructure for your blockchain application. It
allows the function of sending notifications much easier.
At first the blockchain runs on a lambda platform using the
structure or template built and it launches the smart contract on the
blockchain network. This in turn makes the lambda to execute the transactions
that take place in blockchain platform. This is followed by the lambda code you
built following the events that occur in blockchain. The events are in the form
of a data stream and is controlled and managed by kinesis which is then split
into raw and filtered data. The final outcome is visible to the user to meet
the desired requirement.
You build your programming code or decide the code you are going
to use for building the blockchain application. Then you upload your code using
the lambda function to compute the service needed. After you complete this
process, lambda allows the developer to execute the code which in turn allows
the blockchain developer to better manage resources and servers.
This allows the code to run without any obstruction and hassle
free. This takes place immediately right after the code has been approved by
the serverless computational network platform. The building stage cane be
split into three stages as follows.
Building stage
Here the code is groomed to make sure it best suits the
requirements to achieve the desired outcome with the blockchain application to be developed. This
stage can also be called as authoring the code to suit your lambda functions
and code.
In order to do this, first identity the programming languages that
is supported by this AWS service. This service provides tools such as lambda
console, visual studio IDE (integrated development environment), etc. that
allows to author the code better.
Keep in mind to follow that first choose the programming language
you want to use for writing the lambda code to develop the blockchain
application. Second, choose the library you want to use to suit the blockchain
features. So, that the user would feel that the blockchain application is more
feasible to use and interact with.
Amazon services of lambda by itself provide many libraries to
choose from. Choose wisely as to which will help you to develop an
infrastructure that will make the blockchain network more secure. Make sure
that in the process or developing the blockchain application with lambda, there
is no vulnerability to blockchain application after it is built.
Some of these languages are node.js, java, C#, python, etc. and
some of the library variables include lambda task rooter, AWS executive
environment, etc.
Important notes to make sure
Identify what kind of method you want your lambda code to follow
while calling the code to execute a function of blockchain. These methods
include if the code should first obtain and store data or store data and then
obtain further information related to data stored.
Choose the way you want the application interaction to be, as to
how an event that occurs in the blockchain application will be passed to the
user or developer.
Make sure that the interaction between your lambda code and your
blockchain application should be able to obtain and store information. Also,
consider the exception of situations when the network system may fail due to
network error.
After building
Organize all your code and features that depend on the code you
developed for the blockchain application. This is called as a deployment
package. This package ensures that the built plugins and features function and
operate as desired without any failure. Then upload this code to your
blockchain platform and test if the application is working as expected. Make
any changes needed by monitoring and troubleshooting any problems witnessed in
the operation while testing.
Conclusion
Lambda provides the ability to build a strong infrastructure for
blockchain projects. They allow to create decentralized applications with high
level of storage and scalability. Good luck to create your smart and amazing
blockchain application. Get best blockchain development company in usa.
