The Red Hat Build of Quarkus is our Kubernetes-native Java framework, that allows Java developers to continue working in the language they know and love, while being able to work in modern, cloud-native environments, such as serverless.
Historically, Java has been too slow at startup and too memory consuming to be able to be used in serverless environments. Quarkus makes Java ready for containers, by reducing the memory needed at startup, offering near-instant scale-up times, and achieving a much higher workload density.
It also helps boost developer productivity through live reload features and is compatible with popular frameworks like Eclipse MicroProfile and Spring. Bringing Java into the future of application development is a key factor in overall app dev modernization, and Quarkus supports this goal. By having the right tools in place, the process of modernizing applications to better fit into our new, all-digital business landscape can be simplified.
Serverless architectures mean a streamlined, modern application development process, and by allowing Java developers to use the language they already know and love, with no additional training necessary.

Since there is the need to store a private key that holds the funds, it's not feasible to code a solution directly on the client-side. However, I don't want to host any infrastructure or maintain a full-featured Node. For this reason, I come up with the idea of combining blockchain technology with serverless functions.
In this article, I share how I combined blockchain and serverless technologies to create a faucet application using Symbol and Netlify Functions. Do you want to improve developers' onboarding process? Shoot me a message , and let's figure out how to enhance your product developer experience together. Symbol is a next-generation, open-source, decentralized blockchain platform. Thanks to its REST API, developers can integrate blockchain capabilities in new or existing applications with lightweight code using any programming language.
Unlike other blockchain solutions, Symbol does not allow developers to define new smart contracts that will execute on the platform. Instead, the platform provides a predefined set of tested built-in features that solve the most common use cases for using blockchain technology through API calls.
For instance, Symbol comes with plugins to handle asset management, access control, multi-signature and escrow services, and cross-chain swaps, among others. The code that defines a Symbol application remains off-chain. This greatly reduces inherent immutability risk since devs can change parts of the application when necessary instead of defining a rigid contract that cannot change once deployed. Initially, applications were located in servers within the companies facilities.
Now, it's common to hire virtual machines from providers such as Amazon or Google instead of owning the iron at home. Still, developers have to shift the focus from development to configure the servers, virtual machines, or containers to run their applications.
The serverless architecture provides a higher abstraction for devs, enabling them to execute code in an environment entirely managed by others. Executing serverless functions is usually cheaper than running a highly available and distributed server 24 hours a day, considering that functions are charged per-use.
One of the platforms offering Function-as-a-Service FaaS is Netlify , which adds a simplistic configuration layer on top of Amazon Lambda. Instead of hosting a full-featured application in a virtual server, serverless functions can host each piece of code using Symbol features separately. In a single function, we could transform the response returned by the Symbol API, combine different services, and spun a new instance running the code block for each request.
While reading from Symbol blockchain is as straightforward as consuming an API call, things start getting trickier when changing this state of the blockchain is required since nodes only accept serialized data.
We can fill this gap by creating custom serverless functions in plain JavaScript, that later can be consumed by apps written in any other language. Imagine a company willing to integrate Symbol blockchain into their app written in Ruby. It is built atop our investments in blockchain and connects to the compute, data, messaging, and integration services available in both Azure and the broader Microsoft Cloud to provide a robust palette for a developer to realize their vision. Logic Apps and Flow deliver a graphical design environment with more than connectors dramatically simplifying the development of end to end blockchain solutions, and Azure Functions enable the rapid integration of custom code.
A serverless approach also reduces costs and management overhead. With no VMs to manage, built-in scalability, and an approachable pricing model the Azure Blockchain Development Kit is within reach of every developer — from enthusiasts to ISVs to enterprises. Solutions are written using online visual workflow designers and Visual Studio Code , a free download that provides an integrated development environment on Windows, Mac, and Linux.
The resulting applications will run atop a network that has higher rated cloud performance than other large-scale providers and enable federating identities between participants using Azure Active Directory. With Azure, those applications can be deployed to more regions than any other cloud provider and benefit from more certifications. To learn more about how to use these samples to build and extend blockchain applications, you can find a host of videos on our Channel 9 show Block Talk.
Blog Announcements. Introducing the Azure Blockchain Development Kit. Connect To deliver end to end blockchain solutions for consortiums, developers need to enable organizations, people, and devices to connect to the blockchain and do it from a heterogenous set of user interfaces.
Take for example an end to end supply chain for a commodity such as cocoa. SMS and voice interfaces enable small hold farmers in Africa to transact and track their goods at the first mile of the supply chain. Internet of Things IoT devices deliver sensor data to track the conditions of the goods at different points in their journey to market — tracking the humidity in the containers where the beans are held to the temperature of the end product of ice cream that it is incorporated into.
Mobile clients enable logistics providers to accept and transfer responsibility for products on their journey from manufacturer to retail using the compute power that already exists in the pockets of its employees.
Mobile devices also have sensors such as GPS and cameras that can add complementary data that can help attest to the what, where, and when of deliveries. These systems also become clients via extension and need to interact with smart contracts to provide and receive attestable data on behalf of an organization. Bots and assistants enable manufacturers and retailers to interact with the supply chain.
This includes interacting with smart contracts for orders and provenance using natural language and using attestable data from the blockchain to direct actions taken on behalf of a user. Integrate Businesses are using blockchain and smart contracts to facilitate multi-party processes.
It acts like an elastic and limitless storage space for digital data. You can use it anytime you want, and only pay for what you use. There is no need to worry about servers, disks, backup devices, or software to drive all of these. You can turn it on at any time, consume any amount you like, and pay for what you consume. However, somewhere along the way, the Internet has changed for the worse. The peer-to-peer infrastructure think email and ftp is replaced by centralized organizations think Facebook and Dropbox.
Changes are coming. The code just runs. It scales according to the demand. And you pay based on the actual usage. Serverless FaaS is extremely popular. Yet, is AWS Lambda the right technical approach for cloud native serverless computing? One might argue it is far from it. It starts slow the infamous cold start problem , has a lot of overhead an entire OS and stack just to run a single function , and often requires explicit management of server resources so much for serverless.
Outside of the world of big tech, we have an alternative universe of decentralized web. Blockchain and cryptocurrency platforms are often constructed as true serverless FaaS platforms from the get-go. It is designed to be trustless.
Improve utilization, reduce operational requirements, and lower application costs
From serverless a competitive and customer experience perspective, things have to be running seamlessly. Serverless is definitely not suitable for everyone, serverless for many software developers it can be exactly the kind of thing that makes a real change. In blockchain, serverless helps you save money and time on server maintenance and continuous manual scaling. Featured Development. Create account. The development block number processed is stored in Redis using blockchain connectionProfile.
What is a serverless platform?
Native dependencies are built during the serverless install process. There are many trends in architecture and implementation for new Development driven applications. The Blockchain Application Development Kit includes Workbench integration samples in the following areas:. These tools have blockchain the first step for development organizations on serverless journey to re-invent the way they do blockchain. This allows outsourcing even the most complex infrastructure.
AWS Marketplace Webinar: How to optimize your serverless applications using observability solutions
This is then used as the startBlock value on the next action invocation to ensure that events are only processed once. It processes all new blockchain events without further manual steps needed. You can check the status of the processing by looking at the action logs or checking the Redis key used to store the last processed block number.
This tutorial showed you how to process blockchain events using serverless functions on IBM Cloud. You created a Node. This was deployed to IBM Cloud Functions, along with all necessary external libraries and dependencies. This function used Redis to persist processed block numbers between invocations. This function was then connected to the alarm trigger feed.
The trigger feed was configured to automatically invoke the function once a minute. This allowed the function to process all new events without further manual steps or needing to have idle infrastructure waiting for events to occur.

Since most of the Markup is statically generated, if the website is primarily content driven like a magazine or blog it can become extremely scalable. Of course, APIs are key that makes this happen as well. Blockchain takes it one step further, instead of serverless, it is completely decentralized.
Instant updates : Google Firebase provides developers serverless immediate notifications whenever serverless data get updated. To overcome the problem, they development use a lambda function to record transactions on development blockchain. These blockchain include blockchain transactions from multiple parties happening in specific sequences. Read our blog. William Markito Oliveira.
