Basic concept of nginx , Apache Vs Nginx , Nginx as Loadbalancer , Nginx as Reverse proxy , Configuration of nginx as load balancer and reverse proxy .

The document discusses various load balancing options for MySQL databases, including application connectors, reverse proxies, and SQL-aware proxies. It provides an overview of popular load balancers like HAProxy, MaxScale, ProxySQL, MySQL Router, and Nginx. These load balancers aim to improve high availability, performance, and scalability. They handle tasks like health checking, failover, read/write splitting, and query routing. The document analyzes the key features and limitations of each type of load balancer.

This document provides an overview of ProxySQL, a high performance proxy for MySQL. It discusses ProxySQL's main features such as query routing, caching, load balancing, and high availability capabilities including seamless failover. The document also describes ProxySQL's internal architecture including modules for queries processing, user authentication, hostgroup management, and more. Examples are given showing how hostgroups can be used for read/write splitting and replication topologies.

Nginx is a web server which can also be used as a reverse proxy, load balancer, mail proxy and HTTP cache

MySQL 8.0.21 includes several new features and enhancements: 1) It allows disabling of the InnoDB redo log at runtime to improve performance while loading initial data. 2) The JSON_VALUE function was added to extract scalar values from JSON documents. 3) CREATE TABLE...SELECT statements are now atomic and crash-safe operations. 4) Per-user comments and attributes can now be set when creating or updating MySQL user accounts.

SQL Server is a high performance relational engine and provides a highly scalable database platform but due to its complexity, bad programming practices, poor indexing and configuration can be prone to serious concurrency problems, unexpected behaviors, lost updates and much more! In SQL Server 2005, two optimistic concurrency mechanisms were introduced and touted as the solution to all our problems. Now in SQL Server 2012 and SQL 2014 even more have followed including latch free data-structures, but many challenges and problems still remain. Let’s take a long look into the world of SQL Server concurrency and investigate Pessimistic and Optimistic isolation understanding how they work, when you should use them, and more importantly when they can go very wrong. Don't be staring down the wrong end of SQL Server's two Smoking Barrels and join me for this revealing and thought provoking presentation.

Security is often an afterthought; configured and applied at the last minute before rolling out a new system. Instaclustr has deployed Cassandra for customers with many different requirements.

Targeted at beginner to intermediate Node.js developers, this session includes basics for getting started with Node.js before focusing on best practices and more advanced topics. The session finishes with an overview of integration with well-known Node.js frameworks, including the popular objection/relational mapping (ORM) frameworks.

This document provides an overview and comparison of MySQL InnoDB Cluster and MySQL InnoDB ReplicaSet. It discusses the components, goals, and features of each solution. MySQL InnoDB Cluster uses Group Replication to provide high availability, automatic failover, and data consistency. MySQL InnoDB ReplicaSet uses asynchronous replication and provides availability and read scaling through manual primary/secondary configuration and failover. Both solutions integrate MySQL Shell, Router, and automatic member provisioning for easy management.

At the moment MySQL 8 and MariaDB 10.4 are the latest versions of the corresponding database management systems. Each of these DBMSs has a unique set of features, unavailable in its analogue (MariaDB features might be unavailable in MySQL, and vice versa). In this presentation, we’ll cover these new features and provide recommendations re: which application will work best on which DBMS.

At OPEN'15, Serge Frezefond (Cloud Solutions Architect @ MariaDB), gave a presentation on Connect Storage Engine.

The document introduces the Scylla Operator for Kubernetes, which provides a management layer for Scylla on Kubernetes. It addresses some limitations of using StatefulSets alone to run Scylla, such as safe scale down operations and tracking member identity. The operator implements the controller pattern with custom resources to deploy and manage Scylla clusters on Kubernetes. It handles tasks like cluster creation and scale up/down while addressing issues like local storage failures.

The New MariaDB Offering: MariaDB 10, MaxScale and More by Serge Frezefond Presented 26.6.2014 at the MariaDB Roadshow in Paris, France.

This document discusses securing MariaDB installations through socket authentication and user account management. It recommends configuring MariaDB to use socket authentication for the root user instead of passwords to eliminate the need for root password management across servers. It also recommends creating individual user accounts with passwords for applications instead of shared accounts, restricting MariaDB to only listen on localhost, encrypting connections using SSL, and encrypting data at rest. The document provides configuration examples for implementing these recommendations in MariaDB.

For many years, MySQL replication used to be based on binary log events. It was considered that all a slave knew was the exact event and the exact position it just read from the master. Any single transaction from a master could have ended in different binary logs, and also, in different positions in these logs. GTID was introduced along with MySQL 5.6. It has brought, along, some major changes in the way MySQL operates. Every transaction has a unique identifier which identifies it in a same way on every server. It’s not important, anymore, in which binary log position a transaction was recorded, all you need to know is the GTID. Database replication is used to handle multiple copies of data, automatically, from the master database server to slave database servers. If we have changed data or schema in the master database, it will, automatically, update the slave database. The main advantage of replication is that it prevents the data loss. If the master database server is crashed, the exact copy of data will be there in the slave server. In MySQL, you can use MySQL Utility for implementing database replication between master and slave. MySQL Utility is a package that is used for maintenance and administration of MySQL servers. You can install MySQL utility, along with MySQL Workbench, or install it as a stand-alone package. MySQL Replication. This article explains how it is implemented, with an example. In this example, two servers have been used – one master and one slave. Both servers are configured in the same manner with MySQL server and MySQL Utility.
