A review of tools that can be used to design APIs, understand how API design works and to mock infrastructure to test your assumptions. We all know that a happy developer is a powerful ally. The focus of this presentation is on the creation of APIs with the support of tools to achieve this. The goal is to create APIs that are simple for developers to understand and consume, powerful enough to be maintained by your business, in minutes rather than hours.

APIs are the fundamental tenets of the Internet. They enable integrations between different services, and they power the servers that bring our applications to life. API integrations lay at the core of our API-driven world, and delivering successful API integrations is fundamental to sustain it. However, more often than not, API integrations tend to fail due to ineffective development workflows. In this presentation, I want to present various API development workflows that have helped me and my clients deliver successful API integrations. I’ll show how documentation-driven development, using mock servers, robust API testing frameworks, and API visibility tools can help to significantly reduce the chances of API integration failure and to keep errors under control.

Wide adoption of Microservice Architecture presents a whole new set of challenges for us as developers. Some of them are well-known and understood. About others we do not think until they strike us out of the blue and we spend a lot of sleepless nights trying to figure them out. And communication between services in distributed system is one of the latter. During this Microservice Architecture Odesa #TechTalk we will talk about how to prevent your microservices from becoming a modern-world Tower of Babel. We will discuss how to select appropriate communication mechanisms for most common cases in a distributed system, how should we define API contracts for each of them and what tools are available for us to keep them consistent and evolve them over time. We will touch following topics:  REST vs RPC vs Messaging and how not to get lost with your options.  Contract First development and how it can save time in multi-team environment.  SwaggerHub as a single Point of truth for REST API  Best practices for gRPC contracts and how to deal with changes in them. About speaker: Andrii Barsukov is Senior .NET developer at Lohika, with 5+ years of commercial experience in development of microservice applications. Currently participating in development of microservice-based financial system, which includes 20+ microservices developed by 10 separate development teams. And some of the challenges that we faced during its development I'd like to share.

Let's explore why you should have an API, how will it influence your business, why you should think about a monetisation seriously. There are a whole bunch of existing models that can help you find the right fit for your API depending on your roadmap. Finally we take a look at the distribution of APIs to developers. Like any cake, you need to make sure it looks and tastes great to be able to sell it and be a leader!

The serverless movement represents a paradigm shift in our ability to create impressive, scalable web applications and services. Redesigning how triggers can generate and execute events can be an extremely cost-effective solution for microservices and large projects alike. Why serverless? It's less complex, scales easily, and usually costs less. The challenge today is that you may be creating these functions specific to a cloud vendor's API gateway, rather than creating the functions that are most reliable and useful. In this session, you will learn how to create a cloud-agnostic serverless execution backend for your APIs. We will show you how to use Postman APIs with Nimbella’s tooling so you have cloud-agnostic runtime environment that can run in any cloud, including private infrastructure when required. If you are building scalable web applications that you want to deploy on any cloud or private cloud, this is a must-attend session.

This is a session given by Matt Boyle at Nordic APIs 2016 Platform Summit on October 25th, in Stockholm Sweden. Description: We’ve spent a lot of time over the years at Shapeways building, honing, and improving our deployment and test process for our web properties and API. We started with straight-to-prod commits (which caused quite a bit of downtime!), graduated to working in two- and then one-week release cycles (which caused a lot of anxiety!), to where we are today: releasing 5-15 times a day, with automated testing, using continuous improvement and delivery best practices and tools. We’ve taken the complexity and anxiety out of our deployment process by implementing ChatOps, or using a bot to handle the sorts of tasks computers are great at, namely performing complex tasks repeatedly without error. This enables humans to focus on tasks that we’re uniquely suited for, namely solving complex problems and architecting reliable, resilient, and scalable solutions for our users. We’d love to share some of what we’ve learned along the way, from building automated testing tools, to selecting and implementing open-source solutions, to how we took our global deployment process from one hour to 4 minutes. We’d also like to share our vision of the future: what inspires us, what we hope to achieve in the coming weeks, months, and years, and how we’re going about doing it.

"Modern applications are highly distributed. We face challenges related to the use of internal and external APIs and how to build APIs with agility in the face of software that can evolve and change at any time. The API industry proposes two common strategies to circumvent these challenges: API Mocking and Service Virtualization. Both have pros and cons. At Cisco, we came up with the idea of API emulators has a third strategy to handle the challenges we were facing. As a result of our work, we published a reference implementation for Webex ChatBots. In this talk, we'll explain the motivation behind API emulators in the perspective of DevOps, CI/CD, Software Development, and serverless/microservices architectures. I will elaborate on the idea of integrating emulators as part of an overall API strategy, dive into the process of building such emulators, and validating them with Postman."

How many of you have created an API? But how many created a good API? A good API is like a good meal, makes developers extremely happy with a belly full - and for some companies who are API first having a simple, documented, reliable API is crucial. When developers complain about your API it is maybe because you didn't design it well enough - intentions are surely important but design is king. The Rapid API Prototyping talk, is all about bridging the gap between thinking and doing with focus on best practices, tooling and tricks to make developers LOVE your API at first sight.

Rapid Api Prototyping

Kong Inc.

This is a session given by Konstantin Yakushev at Nordic APIs 2016 Platform Summit on October 25th, in Stockholm Sweden. Description: API versioning is a very heated topic in API design world. Common approaches are passing version number explicitly (with a lot of fairly useless discussion on where exactly to put that number) or only introducing backwards-compatible changes. When creating internal API for Badoo applications we found those approaches to be too limiting. Passing version number requires implementers to accommodate for all breaking changes when bumping version – even when it’s not required for business goals of that application at the time. Instead of driving value for business, application developers are in constant race to keep up with the API. Never introducing incompatible changes is also not an option. After several feature redesigns (something that may happen at Badoo once every few weeks) protocol becomes bloated and half of the fields transmitted over the wire start being useless. This talk is about our approach to versioning as part of client-server component negotiation. Client announces features and capabilities it supports and server replies with features status: whether they are enabled or disabled and whether they can be enabled by some user action (e. g. by buying some paid product). Beside those componentized features, client also sends support flags such as SUPPORT_IMAGE_SIZE_VIA_URL which affects how API works. We use those flags where in typical API a version number bump would be required. This approach allows both server and client to understand their current state and adjust their code accordingly – essentially, a tailor-made API for every client. Gathering data on feature and flag support among clients allows us to remove old code branches while continuing to evolve the API. As a result, we are not afraid to change something when that change is required. Old clients continue to work while protocol rot is kept at low level. In this talk I will give details on how exactly this versioning scheme work, how we test those changes, how and when we deprecate our old clients and note some stats and insights from using this scheme at Badoo for several years.

This is a session given by Gustaf Nyman at Nordic APIs 2016 Platform Summit on October 25th, in Stockholm Sweden. Description: In enterprises the majority of APIs are internal and may count in hundreds. APIs are often implemented in and used from a variety of languages and platforms, and legacy system and protocols are ever-present. As APIs are increasingly part of business strategies, API management becomes an important concern of the whole organisation. Gustaf has spent more than 15 years building API infrastructure for enterprises. In this talk, he shares his thoughts on designing and implementing a long-lasting API management strategy.

This is a session given by Michael Kuehne at Nordic APIs 2016 Platform Summit on October 26th, in Stockholm Sweden. Description: It can be tough to test an apparently simple service comprehensively. A microservice architecture brings a new level of complexity to the question “How can we validate that our API is working as intended?” In this talk Michael will explain how to use test driven development for APIs and even further how TDD can drive an API Design towards a more usable design, and how to build an well-tested ecosystem of microservices. This approach is applicable for different kinds of services (REST APIs, websockets, industrial protocols). Independent from the type of interface we always ran into similar problems when we build an ecosystem of services. We have to deal with dependency, asynchronous behaviours, fallback mechanisms, endpoint versioning and sometimes even shared databases. It’s not trivial to apply TDD to these kinds of problems cause you have to think of scenarios. But there are ways of identify these scenarios and to test them. As an API specialist Michael worked with various clients designing, building, testing, maintaining and even redesigning private and public services. Based on his project experience he developed a practical approach to apply TDD to APIs in microservice ecosystems.

This is a session given by Bill Doerrfeld at Nordic APIs 2016 Platform Summit on October 25th, in Stockholm Sweden. Description: At Nordic APIs, our goal is to help businesses make smart tech decisions using APIs. To that end, via events and content Nordic APIs has treaded the business and technical sides to consider holistic best practices for providing an API. In this introductory Summit keynote talk, I’ll introduce what we’ve learned in the form of 6 core tenants of API practice which we’ve also designed this conference to address. Together they define a functional and evolving API: Platformification: Becoming an API-first company means undergoing a platformification process. This represents a global trend that many argue needs to be adopted to keep your business competitive within the digital economy. Strategy: Even before development begins, it’s important to consider your core API strategy. This is a defensible position that aligns your tech with platform goals, strategically exposing internal assets catered to an industry niche. Business Models: APIs have the power to improve efficiency, reduce overhead cost, open up complementary revenue streams, extend R&D, or even alter an existing business model entirely. Thus, you’ll want to determine the right monetization method that improves overall business and leads to end profitability. Security: With new major data breaches reaching the public ear every month, the importance of digital security can never be underestimated. For APIs, much of that lies in monitoring usage, access management, and identity control. Design: No developer wants to use an API with an ugly developer portal, unintuitive URL structures, outdated technology, or terrible lag time. In order to keep your developer consumer happy, paint the API portal and overall developer experience with an aesthetic brush. Marketing: In order to spark adoption, you need to have more than awesome functionality. I’ll review evangelism and discovery techniques you can use to get an API in the hands of more developer users. We’ll look at specific successful implementations of these philosophies in the wild, and mention examples from our blog and eBook content that have brought in industry experts to share their insights. I’ll initiate dialogue and open the conference up to see where we’re heading. What you can get out of embracing the core tenants of API practice?

Microservices architecture overview v2

Dmitry Skaredov

In the last years the microservices architecture style has been gaining traction with some companies such as Netflix, Yelp, Gilt, PayPal. Many of that companies abandoned their previous monolithic architecture and moved to a microservices approach. Does that mean that monolithic architectures are a thing of the past? In this talk we will review some key microservices concepts (and misconceptions), search for the essence of microservices architectures and discuss about different approaches to implement them from the industry.

Elastically scalable architectures with microservices. The end of the monolith?

Javier Arias Losada

Digital transformation is on its way and the industry is required to adopt new concepts and techniques, like the Internet of things (IoT), Cloud and Enterprise Mobility. As a matter of that, new business models arise, which need to be evaluated by companies to not lose market shares and stay in touch with the competitors. Gartner’s vision of Bi-modal IT seems to become more and more the reality, which besides all chances, also brings a lot of challenges companies have to deal with. One essential topic for implementing the ideas of Bi-modal IT is API Management – at least from our point of view. In addition, it is also a key enabler to define a solid strategy, in order to meet the challenges with respect to digital transformation.

Practices and tools for building better APIs

NLJUG

Een belangrijke voorwaarde om goede en leesbare Java code te schrijven is om gebruik te maken van een goede API. Een goede API helpt ontwikkelaars om sneller hoogwaardige code te schrijven. Het ontwerp van een API is daarom belangrijk, zeker als er grotere systemen worden gerealiseerd in teamverband. Moderne ontwikkeltools als Eclipse, IntelliJ IDEA en FindBugs helpen met het schrijven van goede API, en het detecteren van slecht gebruik. Deze sessie gaat in op de laatste ontwikkelingen en mogelijkheden, inclusief nieuwe taalmogelijkheden in Java 8. Er wordt hierbij gebruik gemaakt van praktische situaties en concrete codevoorbeelden, gebaseerd op echte ervaringen in grote codebases. Met praktische tips en toegankelijke tools kan al een grote stap gemaakt worden om in de praktijk beter met API ontwerp om te gaan!

Apache Beam is a top-level Apache project which aims at providing a unified API for efficient and portable data processing pipeline. Beam handles both batch and streaming use cases and neatly separates properties of the data from runtime characteristics, allowing pipelines to be portable across multiple runtimes, both open-source (e.g., Apache Flink, Apache Spark, Apache Apex, ...) and proprietary (e.g., Google Cloud Dataflow). This talk will cover the basics of Apache Beam, describe the main concepts of the programming model and talk about the current state of the project (new python support, first stable version). We'll illustrate the concepts with a use case running on several runners.

This project aims to predict whether a loan application will be approved or denied based on various factors such as applicant's income, credit score, loan amount, etc. Using a dataset containing historical loan application data, we employed machine learning algorithms to build a predictive model. The model was trained on features such as applicant's income, credit history, loan amount, loan term, and others. After training the model, we evaluated its performance using metrics like accuracy, precision, recall, and F1 score. The insights from this project can help financial institutions streamline their loan approval process and make informed decisions.
