Feed: Microsoft Azure Blog. Author: Bert Van Hoof. One of the most dynamic landscapes embracing Internet of Things (IoT) is the modern city. As urbanization grows, city leaders are under increasing pressure to make cities safer, accessible, sustainable, and prosperous. Underlying all these important goals is the bedrock that makes a city run: infrastructure. Whether it be water, electricity, streets, traffic lights, cities are increasingly using the Internet of Things (IoT) to manage their infrastructure by capturing and analyzing data from connected devices and sensors. This gives city managers real-time insights to improve operational efficiency and outcomes and to altogether ... Read More

Feed: Planet MySQL; Author: Tiago L. Alves; Gaming, banking, telcos, and online services all are powered by fully-redundant and fault-tolerant software systems. At the heart of those systems, you can find MySQL Cluster — a distributed in-memory database having a minimum of five-9s availability (around 5 minutes a year). This open-source database provides nearly-linear scalability and real-time querying predictability at the microsecond level.To achieve such higher availability it’s crucial to ensure that each release is thoroughly validated. Thousands of automated tests are run daily, for different versions and platforms to ensure defects are detected early and fixed. Testing is everyone’s ... Read More

Feed: Clustrix Blog. Author: MariaDB. This is the first in a series of short lightboard talks highlighting popular database topics. In this five-minute session, you’ll learn how the MariaDB MaxScale database proxy works with multiple MariaDB instances to support high availability using a primary/replica architecture. Video Transcript Hi, my name is Manjot Singh. I’m here to talk to you about MariaDB’s classic replication model. A lot of times you have a primary server and you have an application. That application connects to that primary server and does its work – it saves data, reads data. And what you may have ... Read More

Feed: The Information Lab. Author: Robbin Vernooij. 9 November, 2019 | Robbin Vernooij Tableau HA environment, load balancer and PostreSQL Problem I recently come across a tableau HA (High Availability) environment where a load balancer (you might guess it already…) divides the load of tableau traffic over multiple tableau servers. We ran into an issue where we COULD connect to the PostgreSQL DB to hook up our user stats and server health views, but upon uploading them, the server COULDN’T reach the data source any longer. Turns out the tableau servers within the HA and load balancer environment see one ... Read More

Feed: AWS Compute Blog. Author: Sandy Carter. We love SQL Server running on AWS almost as much as our customers. Microsoft SQL server 2019 became generally available on November 8, 2019, and is now available to on AWS. More customers run SQL Server on AWS than any other cloud, and trust AWS for a number of reasons. The first is performance. Recent performance benchmarks show that AWS delivers great price-performance for running SQL server. ZK Research points out that SQL Server on AWS consistently shows a price performance using HammerDB, a TPC-C-like benchmark tool compared to Azure, that’s over two ... Read More

Feed: Planet MySQL; Author: Severalnines; The cloud provides very flexible environments to work with. You can easily scale it up and down by adding or removing nodes. If there’s a need, you can easily create a clone of your environment. This can be used for processes like upgrades, load tests, disaster recovery. The main problem you have to deal with is that applications have to connect to the databases in some way, and flexible setups can be tricky for databases - especially with master-slave setups. Luckily, there are some options to make this process easier.  One way is to utilize ... Read More

Feed: AWS Architecture Blog. IntroductionWhen an IT team first contemplates reducing on-premises hardware they manage to support their workloads they often feel a tension between wanting to use cloud-native services versus taking a lift-and-shift approach. Cloud native services based on serverless designs could reduce costs and enable a solution that is easier to operate, but appears to be disruptive to end user processes and tools. A lift-and-shift migration, though it can eliminate on-premises hardware and maintain existing workflows, doesn’t eliminate the need to manage a server infrastructure, does nothing to improve a team’s agility in releasing enhancements after migration to ...

Feed: Microsoft Azure Blog. Author: Julia White. Enterprises rely on a hybrid technology approach to take advantage of their on-premises investment and, at the same time, utilize cloud innovation. As more business operations and applications expand to include edge devices and multiple clouds, hybrid capabilities must enable apps to run seamlessly across on-premises, multi-cloud, and edge devices, while providing consistent management and security across all distributed locations. Without coherence across these environments, cost and complexity grow exponentially. At Microsoft, we understand that hybrid cloud capabilities must evolve to enable innovation anywhere, while providing a seamless development, deployment and ongoing management ... Read More
