Considerations for modernizing Microsoft SQL database service with high availability on AWS

Feed: AWS Architecture Blog. Many organizations have applications that require Microsoft SQL Server to run relational database workloads: some applications can be proprietary software that the vendor mandates Microsoft SQL Server to run database service; the other applications can be long-standing, home-grown applications that included Microsoft SQL Server when they were initially developed. When organizations migrate applications to AWS, they often start with lift-and-shift approach and run Microsoft SQL database service on Amazon Elastic Compute Cloud (Amazon EC2). The reason could be this is what they are most familiar with. In this post, I share the architecture options to modernize ... Read More

High Availability and Observability Using Red Hat Advanced Cluster Management for Kubernetes

Feed: AWS Partner Network (APN) Blog. Author: Vani Eswarappa. By Vani Eswarappa, Partner Solutions Architect – AWSBy Mayur Shetty, Principal Solution Architect – Red Hat Red Hat As container usage increases in application modernization efforts, Kubernetes plays an important role in managing container-based applications. Enterprise organizations operating and serving customers at scale often require a multi-cluster approach to meet their growing demands and performance. However, managing these multi-cluster life cycle, application deployments, and enforcing security policies across clusters is often challenging and time consuming. Red Hat is an AWS Partner and leading provider of enterprise open source solutions, including high-performing ... Read More
High availability, load balancing and troubleshooting the Vnet gateway.

Feed: Microsoft Power BI Blog | Microsoft Power BI. Author: . We recently added the capability to create Vnet data gateway clusters. You can use a cluster of virtual network data gateways to load balance the queries executing on the cluster and to avoid a single point of failure. We also added the capability to change the time until auto-pause when the Vnet is inactive. This way you can ensure that your Vnet gateway is active when you need it. We also added the capability to troubleshoot the VNet data gateway. You can troubleshoot your virtual network data gateway network ... Read More
Amazon Relational Database Service now supports Multi-AZ deployments on AWS Outposts for High Availability
Feed: Recent Announcements. Amazon Relational Database Service (Amazon RDS) now supports highly available configurations with Multi-AZ deployments for PostgreSQL and for MySQL on AWS Outposts in all commercial regions. Amazon RDS Multi-AZ on Outposts deployments provide enhanced availability and durability for RDS database (DB) instances, making them a natural fit for production database workloads. When you provision a Multi-AZ database instance, Amazon RDS automatically creates a primary DB Instance and synchronously replicates the data to a standby instance on a second AWS Outposts connected to a different Availability Zone (AZ). Each Outposts runs on its own physically distinct, independent infrastructure, and ... Read More
Achieving Geo-Distribution and High Availability with Redis and Azure
Feed: Redis. Author: Suzanne Kenney. In today’s age, modern enterprises require their applications to have high availability across the globe. Thankfully, ensuring high availability for their customers all over the world doesn’t have to be complicated. In this webinar, join Redis and Microsoft to learn how to configure and leverage Active-Active geo-distribution on the Azure Cache for Redis Enterprise platform. Active-Active deployment allows businesses to create global applications that provide local sub-millisecond read/write latencies with considerably better resilience to failure. During this session, you’ll learn the differences between Azure Cache for Redis and the Azure Cache for Redis Enterprise tiers ... Read More
Failover and High availability with MariaDB Connector/J for 2.x driver
Feed: MariaDB Knowledge Base Article Feed. Author: . This guide will cover: The load balancing and high availability concepts in Mariadb Connector/J for version before 3.0 The different options. Failover and high availability were introduced in 1.2.0. Failover occurs when a connection to a primary database server fails and the connector opens up a connection to another database server.For example, server A has the current connection. After a failure (server crash, network down …) the connection will switch to another server (B). Load balancing allows load (read and write) to be distributed over multiple servers. In MariaDB (and MySQL) replication, ... Read More
Shaun M. Thomas: PG Phriday: Defining High Availability in a Postgres World
Feed: Planet PostgreSQL. What does High Availability actually mean when we’re discussing Postgres clusters? Sure, we can set an RPO, RTO, SLA, and other 3-letter acronyms regarding expectations and deliverables, but what are we trying to achieve? Fast failover? No lost transactions? Both? What about time necessary to rebuild or reclaim a former Primary node? How do all of our various replication configurables affect this?Let’s see if we can come up with a definition of High Availability that’s suitable to a Postgres context. This may seem a trivial exercise at first, but there’s a method to our madness. Starting from ... Read More
Sergey Pronin: High Availability and Disaster Recovery Recipes for PostgreSQL on Kubernetes

Feed: Planet PostgreSQL. Percona Distribution for PostgreSQL Operator allows you to deploy and manage highly available and production-grade PostgreSQL clusters on Kubernetes with minimal manual effort. In this blog post, we are going to look deeper into High Availability, Disaster Recovery, and Scaling of PostgreSQL clusters. High Availability Our default custom resource manifest deploys a highly available (HA) PostgreSQL cluster. Key components of HA setup are: Kubernetes Services that point to pgBouncer and replica nodes pgBouncer – a lightweight connection pooler for PostgreSQL Patroni – HA orchestrator for PostgreSQL PostgreSQL nodes – we have one primary and 2 replica nodes ...
