AppSphere 15 - Containers and Microservices Create New Performance Challenges

Are you being asked to put more cloud in your strategy? If you’re like most people, the answer is a definite yes. The word “cloud” can mean so many things, however, that making an actionable strategy is impossible. At Pivotal, we divide cloud into two distinct parts: migrating as many legacy applications into SaaS as possible and focusing on perfecting the software you build in-house that runs your business. Gartner is predicting that by 2020, 75% of applications used to support digital businesses will be built in-house. If you’re one of these companies, you’ll need to quickly evaluate how you develop and run your custom written software. We believe that soon, every company will either be a software company or losing to a competitor who is. It’s time to focus on the craft of managing the software development life-cycle, and this brief, but dense webinar will help launch your efforts to become a software defined business. Join us in the last installment in our series: Organization Transformation - to get the full benefit of a cloud native approach, you'll likely need to change how your organization functions and behaves: you'll have to change its culture. When software is thought of more as ongoing products instead of discrete projects, the way the IT department is managed and run changes accordingly. This last part covers the motivations for those changes and outlines how to start transforming everyday management, strategy, staffing, and operations to become a cloud native enterprise. Presenter: Michael Coté

The document provides an overview of microservices architecture including: - Definitions and characteristics of microservices such as componentization via services, decentralized governance, and infrastructure automation. - Common drivers for adopting microservices like agility, safety, and scalability. - Guidelines for decomposing monolithic applications into microservices based on business capabilities and domain-driven design. - Discussion of differences between microservices and service-oriented architecture (SOA). - Ecosystem of tools involved in microservices including development frameworks, APIs, databases, containers, and service meshes. - Common design patterns and anti-patterns when developing microservices.

The document discusses changing views on integration from traditional approaches using enterprise service buses to more modern approaches using API gateways, serverless computing, and integration platforms as a service (iPaaS). It covers integration patterns like vertical integration for synchronous APIs and horizontal integration for asynchronous integration between systems. Event-driven integration using message queues is discussed as a third dimension of integration. The use of cloud-native approaches and integration platforms out of the box is presented as an alternative to traditional monolithic integration middleware.

The document discusses strategies for evolving monolithic applications into microservice architectures. It notes that modern software needs to meet increasing demands around release frequency, developer velocity, and infrastructure costs. While classical architectures based on monoliths and service-oriented architectures were effective, they no longer address today's challenges. The document then introduces microservices as an alternative, describing characteristics like independent deployability, language/data agnosticism, and process isolation. It acknowledges that while building individual microservices is straightforward, the difficult part is designing the overall system architecture and operational capabilities required to manage many interconnected microservices. Lagom is presented as one framework that can help implement reactive microservices on the JVM.

Presenting key architectural concepts of the Microservices Architecture(MSA) and how you can use those architectural principles in practice.

Developer experience is about reducing friction between creating an idea and delivering business value in production. It includes factors like lead time, deployment frequency, and monitoring. DevEx has three components: workflow, platforms, and the developer experience itself. The ideal workflow follows progressive delivery principles. Teams should focus first on automating the inner development loop and CI/CD processes, then on observability and best practices. Questions around local vs cluster development, verification approaches, and whether to provide guardrails can help guide platform design decisions.

Do microservices force us to look differently at the way we lay down and evolve our integration architecture, or are they purely about how we build applications? Are microservices a new concept, or an evolution of the many ideas that came before them? What is the relationship between microservices and other key initiatives such as APIs, SOA, and Agile. In this session, we will unpick what microservices really are, and indeed what they are not. We will consider whether there is something unique about this particular point time in technology that has enables microservice concepts to take hold. Finally, we will look at if, when, where and how an enterprise can take on the benefits of microservices, and what products and technologies are applicable for that journey.

SpringOne Platform 2016' Speakers: Mallika Iyer; Principal Software Engineer, Pivotal & Sam Weaver; Product Manager, MongoDB The ability to provide your organization with multiple data services on a platform like Pivotal Cloud Foundry is very powerful, and increases the agility of the organization as a whole, when developers are able to provision data services on demand, and all of this is completely transparent to the system operators. This session will cover a very brief overview of Pivotal Cloud Foundry, and will then deep dive into running MongoDB as a managed service on this platform. The MongoDB service for Pivotal Cloud Foundry leverages the capabilities of Bosh 2.0 for on-demand-dynamic provisioning for services while maintaining an integration with MongoDB's Cloud Ops Manager, to provide the best of both - Pivotal Cloud Foundry and MongoDB.

Today, every one of us wants to get things done fast. The fact of the matter is Serverless is a fantastic platform for doing things fast. Because, with Serverless, you really don’t have time to waste in terms of delivering your business value. Turns out you can with the right cloud services. In this talk we’ll create a microservice using Azure Functions and also get introduced to bigger picture of serverless computing. I presented this session in Global Azure Bootcamp 2019 in Dublin. #GlobalAzure #AzureFunctions #Serverless

Serverless, aka. function-as-a-service (FaaS) is on-trend, and as with all new shiny things it is often both over and under estimated in the space of the same conversation. Where can and should it be applied, especially in relation to integration? Does it make provide a good platform for implementing APIs? What type of application would be appropriate to put on it? How does it relate to similarly elastic architectures such as microservices? If its functions are stateless, where and how do you manage state. How do you integrate to and from it? What are the benefits, and what are the limitations? This unique perspective is from the same experienced team that provided key clarifications on the comparisons between microservices, SOA and APIs. 

At a high level, both SOA and web APIs seem to solve the same problem – expose business function in real-time and in a reusable way. This tutorial looks at how these initiatives are different and how they align into an evolving integration architecture. It discusses how API Management differs from the integration architectures that came before it, such as SOA and EAI.

From Multi-Cloud and MicroServices to12-Factor Apps, Cloud-Native Applications are designed to be fast, tested and fail safe with continuous deployment to production. Simple policy declaration and enforcement across your stack allow you to move at greater speed, safety, and scale.

Integration Cloud Service (ICS) provides a cloud hosted means to integrate systems together using a graphical means to define and represent integrations. This presentation sets out to demonstrate how ICS can be used to effectively implement integrations that work both in the cloud and on-premise. This presentation will discuss different customer best practices, showing the audience how to implement integrations with ICS and talk about patterns, challenges and give useful insights into ICS. This should equip the audience with the knowledge on how to use ICS to solve their own integration needs such as removing those tedious manual processes of moving data from one system to another with automation through integration.

The document discusses how digital transformation is driving changes in enterprise integration needs, moving from centralized integration middleware towards decentralized microservices and micro-integrations. It introduces Ballerina, a new programming language from WSO2 that can be used to build independent, lightweight integration microservices visually or textually. WSO2's next generation integration platform will use Ballerina to replace the ESB and address modern integration requirements around agility, orchestration, APIs, microservices, performance and scalability.

This document discusses moving from traditional monolithic and SOA architectures to microservices architectures. It covers principles of microservices like high cohesion, low coupling, independent deployability and scaling of services. It also discusses organizational implications, noting that teams are typically organized around business capabilities rather than technical layers in a microservices structure. Key challenges of microservices like increased complexity and performance overhead are also outlined.

Next Steps in Your Digital Transformation This session brings together all the lessons learnt throughout the day and shares with you practical advice on how to get started with, or accelerate, your journey to become a digital business.

Swarm allows multiple Docker hosts to be clustered together into a single virtual Docker host. It provides features like scheduling, rescheduling on failure, high availability with multiple masters, and service discovery. To set up a Swarm cluster, run the Swarm manager container on one host and restart the Docker daemons on the other hosts with arguments to join the cluster. An example voting app microservices demo shows how to deploy an application across a Swarm cluster.

Prometheus is a next-generation monitoring system with a time series database at it's core. Once you have a time series database, what do you do with it though? This talk will look at getting data in, and more importantly how to use the data you collect productively. Contact us at prometheus@robustperception.io

The document discusses how HipChat improved their web client development process. It describes moving from a monolithic codebase with no testing to using React for component-based development with JSX syntax. This improved reusability, performance, and made the code easier to read. It also implemented Flux architecture and separated concerns into stores, actions, and dispatcher. Additional improvements included using Webpack for builds, Gulp for testing and documentation, and feature branches to streamline development and deployment. These changes allowed HipChat to deploy the web client more frequently and identify issues faster.
