DevOps Braga #12 discussed infrastructural challenges at a fast-growing startup and solutions implemented by the DevOps team. The startup had storage issues with large VMs and a monolithic infrastructure across regions. The team rethought the infrastructure, moving to smaller VMs with horizontal scaling, SMB file sharing, and an HAProxy load balancer. They also discussed implementing containers to build a microservices-oriented pipeline with autonomous CI/CD environments for each team.
You can only monitor systems that you know!
GLPI is a very successful open source ITSM solution, the project follows a modular approach and can therefore be extended by many very useful plugins. And yes … GLPI is mainly “French” !
In this very short introduction, I’ll will give you a rapid overview how to:
– automate your IT inventory to manage pc’s, servers, vm’s, vmware, …
– add printers and network components via “snmp”
– add special assets like databases, appliances, URL’s, lines, racks, datacenters…
– add additional information’s to all this components
– add people from your LDAP / AD
– add plugins to GLPI
– build reports
– import / export your data
– handle tickets, problems, changes, or projects
In my second presentation “Monitoring @ G&D ” I will later show you how we’ve automated our monitoring with the help of GLPI, some db view’s and python scripts.

Talk given at OpenResty Con 2017 in Beijing.
Kong (https://getkong.org) is a widely-adopted open source API Gateway built with OpenResty. It aims at helping secure, manage, and extend microservices-based architectures with minimal effort from the user, while ensuring platform agnosticism.
In this talk, we will explore the challenges we encountered developing such an OpenResty application, and how we overcame many of them by way of libraries and contributions back to the OpenResty community. We will cover topics such as clustering OpenResty nodes, inter-workers communication, DNS resolution, typical pitfalls OpenResty developers should avoid, and much more.
Continuous delivery model sounds great to almost everyone, but is not that easy to implement when real life comes into play. On the one hand, AEM architecture feels like a good fit for this strategy (everything is content after all, right?), but on the other hand we all know how challenging even individual deployment can get. Content management system itself is often just a fraction of your concern - you have to build it first, test it, stitch all the elements up and then figure out how to deliver your code in a repeatable and controlled way to production.
Throughout the last couple of years we’ve been trying really hard at Cognifide to make continuous release and delivery possible for AEM. It was a bumpy and twisty road, but we finally made it. During my talk I’d like to show you how we build AEM platforms these days using open source tools, including:
- Terraform to define and manage infrastructure as code
- Chef to describe deployments in an approachable way, which enforces consistency & repeatability across environments
- Consul that helps us discover services around and mitigate failures
- Jenkins & GoCD to orchestrate delivery model

Pragmatic Monolith-First, easy to decompose, clean architecturePiotr Pelczar
Designing systems architecture corresponding to business needs in long future is like a reading tea leaves. There is no common way to design systems. Making decision to start project with microservices may make refactoring much harder and introduce too much complexity in the infrastructure layer and finally slow down development. However maintaining a monolith is a tough nut to crack.
Let’s see how to build a system starting from well organized monolith with well marked technical and business scopes that enables to make a decision in with way it should be decomposed and how to deliver it. Strategic and tactical techniques from Domain-Driven Design and Hexagonal Architecture will be used. I will show you how to monitor accidential complexity using different tools during CI.
I invite you if you are interested in building systems with complex business domains.

At Adobe APIs are powering the next generation of Creative applications.
Mesos makes it very easy and fun to deploy and run Robust and Scalable Microservices in the Cloud. Today's technologies offer simple solutions to create RESTfull services while Mesos brings them to life faster.
As the number of microservices increase and the inter communication between them becomes more complicated, we soon realize we have new questions awaiting our answers: how do microservices authenticate ? how do we monitor who's using the APIs they expose ? How do we protect them from attacks ? How do we set throttling and rate limiting rules across a cluster of microservices ? How do we control which service allows public access and which one we want to keep private ? How about Mesos APIs and its frameworks ? Can they benefit from these features as well ?
Come and learn a scalable architecture to manage microservices in Mesos by integrating an API Management layer inside your Mesos clusters. This presentation will show you what an API Management layer is, what it's composed of and how it can help you expose microservices in a secure,managed and highly-available way, even in multi-Mesos cluster setups.
During this session you will also have the opportunity to learn how Adobe's API Platform solved this problem, where it is today and what it envisions do to with Mesos further.
If you're working with microservices already or you're creating new ones then this presentation is for you. Come and learn how Mesos together with an API management layer will make you a microservices hero in your organisation. At Adobe APIs are powering the next generation of Creative applications.

Serverless in production, an experience report (FullStack 2018)Yan Cui
AWS Lambda has changed the way we deploy and run software, but this new serverless paradigm has created new challenges to old problems - how do you test a cloud-hosted function locally? How do you monitor them? What about logging and config management? And how do we start migrating from existing architectures?
In this talk Yan and Scott will discuss solutions to these challenges by drawing from real-world experience running Lambda in production and migrating from an existing monolithic architecture.
Docker on a local machine and Docker in production — are two big differences. It's easy to play with technology but it's hard to do something real for many customers.
Half a year ago inside of Alpha Laboratory (division of Alfa-Bank) we've started building new microservices architecture for one of our pilot projects. We've almost completely changed a stack of the used technologies on a frontend and significantly changed it on a middle layer. For package and distribution we have choosen Docker. Two months ago we've deployed project to production and have opened service for clients.
In the report the following topics will be covered:
- reasons of a choice Docker;
- why Docker without other tools is not enough for a production;
- what stack of technologies we used in our solution;
- what advantages we've got;
- what problems have been faced and how we've solved them.

Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors.
Wireless communication is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal through wireless communication technologies and devices.
Features of Wireless Communication
The evolution of wireless technology has brought many advancements with its effective features.
The transmitted distance can be anywhere between a few meters (for example, a television's remote control) and thousands of kilometers (for example, radio communication).
Wireless communication can be used for cellular telephony, wireless access to the internet, wireless home networking, and so on.
