Vietnam Open Infrastructure User Group

This document provides tips for becoming a "cool dad" through home automation. It discusses the author's experience transforming his home into a smart home using various devices that communicate over different protocols. Some challenges discussed are the separate apps required for each device, latency issues, security concerns, reliability, and ensuring a good user experience. The author advocates for a home automation system that is event-driven, runs locally at the edge rather than in the cloud, and focuses on simplicity rather than requiring users to adapt to the technology.

Vietnam Open Infrastructure User Group

Vitastor is a fast and simple Ceph-like block storage solution that aims to maximize performance for SSDs and NVMEs. It focuses on block storage with fixed-size blocks rather than Ceph's object storage model. Vitastor uses a monitor, Etcd, and OSDs like Ceph but without a separate CRUSH layer and with monitors that do not store data. It supports technologies like RDMA for low latency and high throughput. The presenter's experiments showed Vitastor had improved performance over Ceph in some tests but also experienced some integration and operational issues.

Vietnam Open Infrastructure User Group

This document discusses Zero touch on-premise storage infrastructure with OpenStack Cinder. It describes Viettel's IT infrastructure with mixed storage resources and the challenges of managing it. The solution presented uses OpenStack Cinder and additional tools to automate the management and provisioning of block storage for bare metal servers and OpenStack instances. This removes manual configuration steps and improves performance by pre-zoning storage connections. The goal is to make volume management simpler and allow adding new storage resources without additional configuration through the unified management solution.

Room 2 - 7 - Lã Mạnh Hà - Agile + DevOps = A great combination

Vietnam Open Infrastructure User Group

Agile and DevOps are a great combination for software development. When combined, Agile adds structure to planned development work while DevOps incorporates unplanned work from operations teams. This allows for iterative development in small batches with test and delivery automation. It also improves team workflow by giving all members knowledge of the full development and operations lifecycle. Key practices include involving operations in sprint planning, automating workflows, implementing service backlogs under DevOps principles, using infrastructure as code tools, and including quality assurance at each phase. Measurement of outcomes helps ensure continuous improvement when applying Agile and DevOps together.

Room 2 - 1 - Phạm Quang Minh - A real DevOps culture in practice

Vietnam Open Infrastructure User Group

The document discusses establishing a true DevOps culture and environment. It begins by describing the traditional battle between developers and operations staff. DevOps aims to resolve this conflict by having developers and operations work together across the entire application lifecycle. The document then outlines some of the challenges in implementing DevOps and presents steps for establishing a true DevOps environment, including having a common language, planning infrastructure and processes together, coding to DevOps best practices, coordinating deployments, and centralizing monitoring and logs. Key aspects are involving all teams early, sharing information transparently, and avoiding prioritizing specific tools over collaboration.

Room 2 - 5 - Seong Soo - NHN Cloud - Upstream contribution mentoring program ...

Vietnam Open Infrastructure User Group

This document describes the OpenStack Korea User Group's efforts to establish an upstream contribution mentoring program. It details how they struggled at first due to a lack of experience, but were eventually able to contribute by starting small, such as adding columns to the OpenStack client output and fixing test cases. Over two years, they developed a contribution academy program where mentees analyzed the OpenStack client code, mapped out unimplemented commands, and implemented some themselves. As a result of this ongoing mentoring effort, they have contributed several bug fixes, issues, new commands, and documentation improvements to the OpenStack upstream project.

Vietnam Open Infrastructure User Group

The document discusses using Senlin, an OpenStack clustering service, to provide autoscaling capabilities for multicloud platforms. Senlin allows for managing clusters of nodes across different cloud providers and includes features like load balancing, auto-healing, and scaling policies. It describes how Senlin was implemented at a company to provide a centralized autoscaling solution across OpenStack and VMware cloud environments. Some drawbacks of Senlin are also outlined, along with potential future work like multi-region clusters and global load balancing.

Room 1 - 3 - Lê Anh Tuấn - Build a High Performance Identification at GHTK wi...

Vietnam Open Infrastructure User Group

This document discusses solutions for generating unique identifiers at high speeds. It compares auto-increment, UUID, hash, and Snowflake approaches. Snowflake is highlighted as able to generate up to 4 billion IDs per second while maintaining order, supporting distribution and sharding, and providing security benefits. The document outlines how Snowflake works by combining a timestamp, node ID determined via file, random number, IP address or ZooKeeper, and an increasing sequence number stored in Redis to generate the IDs at high speeds with strong ordering properties.

Room 1 - 7 - Lê Quốc Đạt - Upgrading network of Openstack to SDN with Tungste...

Vietnam Open Infrastructure User Group

This document discusses upgrading an Openstack network to SDN with Tungsten Fabric. It evaluates three solutions: 1) using the same database across regions, 2) hot-swapping Open vSwitch and virtual routers, and 3) using an ML2 plugin. The recommended solution is #3 as it provides minimum downtime. Key steps include installing the OpenContrail driver, synchronizing network resources between Openstack and Tungsten, and live migrating VMs. Topology 2 is also recommended as it requires minimum changes. The upgrade migrated 80 VMs and 16 compute nodes to the SDN network without downtime. Issues discussed include synchronizing resources and migrating VMs between Open vSwitch and virtual routers.
