High availability and performance are the key aspects when choosing the web hosting provider. If you have a heavy website, there are a lot of processing like importing, exporting, calculations, etc. As a result, chances to max out the CPU and disk are the mortal enemy of real-time transactions. Your website visitors also demand a fast loading time, and if you are unable to resolve this issue, this leads to loss of interest from your visitors, loss of sales and loss of SEO rank.
A virtual private network (VPN) is a secure and encrypted connection between two networks and individual users that protects your internet connection and privacy online. OpenVPN is a free and open-source VPN protocol that implements techniques to create secure point-to-point in routed configurations. It is cross-platform and compatible with all major operating systems.
These days high availability and database clustering are very important for highly loaded production applications. If your server is down for a fraction of time, you are losing customers and money. Therefore making a database environment highly available has typically one of the highest priorities. Set up a highly available cluster is not easier for any developers and system administrators.
SSH is a “Secure Shell Protocol” used to connect and manage remote Linux systems securely over an unsecured network. It is very useful for system administrators to perform day-to-day tasks on the remote server. So securing an SSH server is an essential part of any system administrator.
By default, you can connect to SSH with a password or using the private key. That means, it is only a single factor authentication. So it is a good idea to implement multi-factor authentication in the SSH server to add an extra layer of security. In multi-factor authentication, you will need to provide your system user password and another password generated on a mobile device. This will significantly enhance your server’s security.
Redis is an open-source and in-memory data structure store that can be used for caching, real-time analytics, searching, and machine learning. Integrate Redis with PHP and MySQL will improve your application performance because Redis stores data in RAM.
You can use it with databases like MySQL or MariaDB. Redis provides a mechanism to cache your queries. For example, when a user requests your application page the first time, a MySQL query is performed on the server, and Redis caches this query to RAM. When another user requests the same page, you don’t need to query the database again.
