Charity Hound - Serverless, NoOps, The Tooth Fairy
Presented at ServerlessConf NYC2016.
A common misconception is that "serverless" development means you no longer have to think or care about operations. This could hardly be more false. You are trading one set of problems -- building and running backend services -- for another set, where you are dealing with a sprawling mess of APIs, black boxes and opaque complex systems into which you have limited visibility and even less ability to fix things, along with cotenancy issues and usage caps. The glorious future comes with tradeoffs, and this means application developers need to get better at ops.

Concurrency at Scale: Evolution to Micro-Services
Most large-scale web companies have evolved their system architecture from a monolithic application and monolithic database to a set of loosely coupled micro-services. Using examples from Google, eBay, and KIXEYE, this talk outlines the pros and cons of these different stages of evolution, and makes practical suggestions about when and how other organizations should consider migrating to micro-services. It concludes with some more advanced implications of a micro-services architecture, including SLAs, cost-allocation, and vendor-customer relationships within the organization.
The "Why", "What" and "How" of Microservices
This document discusses microservices and alternatives to monolithic architectures. It begins by outlining the costs of software maintenance for monoliths and reasons why architectures need to change to adapt quickly. Alternatives like SOA are discussed, but microservices are presented as a way to break applications into fine-grained, independent services. However, the document cautions that simply breaking a monolith into smaller pieces does not automatically achieve decoupling, and improper use of microservices could result in even greater complexity. Autonomous services with explicit boundaries and asynchronous communication are emphasized as important characteristics to achieve decoupling.
Microservices architecture ext
My talk @ T-Mobile for the B2B and Commissions teams as part of T-Mobile's move to Uncareer architecture and obsessive customer focus. This effort is to define a path for these two team to move from the current way of Monoliths to a more distributed Microservice architecture while understanding the landmines/risk on the way. Also has a mention of event sourcing architecture and CAP theorem
Microservices and Docker: Foundation for a New Generation of Applications
Docker has matured and expanded from its primary use in the build/test stages into production deployments. Similarly, microservices are expanding from use mostly for greenfield web services to use in the enterprise as organizations explore ways to decompose their monolith to support faster release cycles. Anders Wallgren says that running microservices-based applications in a containerized environment makes a lot of sense—for both build and test, and from a runtime perspective in production. Docker and microservices are natural companions, forming the foundation for a new generation of applications. However, managing microservices and large-scale Docker deployments pose unique challenges for enterprise IT. Join Anders as he discusses patterns for microservices-based architectures and what makes Docker such a good fit for microservices. He explores how to operationalize Docker orchestration, autoscaling and disaster recovery in large-scale production environments, and best practices for Docker configuration and registry management to ensure consistency throughout the pipeline and stability in production. Anders offers tips and tooling for monitoring and managing clusters of containers as a single distributed application and more.
SD-WAN for Public & Private Clouds - VeloCloud
The enterprise WAN is adapting to address the pervasive availability of broadband Internet, the shift of applications to the cloud and the increasing demands for real-time, online and critical applications in the branch office.
At the same time enterprises have made significant investments in their existing WAN architecture infrastructure network equipment and WAN services. Many enterprises are evaluating an SD-WAN solution as a way to address the changing enterprise landscape without decommissioning their existing WAN any time soon.
This webinar guides you through various flexible architectures and transition steps for SD-WAN that target maximum return while minimizing disruption and risk. Examples of how a cloud-delivered SD-WAN enables flexible transition and deployment in both hybrid and Internet only branches will be shared.

Dublin Microservice "Introduction to Service Meshes"
While service meshes may be the next "big thing" in microservices, the concept isn't new. Classical SOA attempted to implement similar technology for abstracting and managing all aspects of service-to-service communication, and this was often realized as the much-maligned Enterprise Service Bus (ESB). Several years ago similar technology emerged from the microservice innovators, including Airbnb (SmartStack for service discovery), Netflix (Prana integration sidecars), and Twitter (Finagle for extensible RPC), and these technologies have now converged into the service meshes we are currently seeing being deployed.
In this talk, Daniel Bryant will share with you what service meshes are, why they are (and sometimes are not) well-suited for microservice deployments, and how best to use a service mesh when you're deploying microservices. This presentation begins with a brief history of the development of service meshes, and the motivations of the unicorn organisations that developed them. From there, you'll learn about some of the currently available implementations that are targeting microservice deployments, such as Istio/Envoy, Linkerd, and NGINX Plus.
