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

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

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

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

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

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

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 ...
