Application Acceleration

Description

The Huawei Cloud EulerOS 2.0 image supports application acceleration. You can use this type of image to optimize performance of Nginx, Redis, MySQL, Memcached, and PostgreSQL applications.

When purchasing ECSs, if you select the Huawei Cloud EulerOS 2.0 image and enable application acceleration, the system will provide performance tuning for the ECSs in terms of CPUs, memory, network, storage, and kernels. This tuning will deliver over 20% higher performance for Nginx, Redis, MySQL, Memcached, and PostgreSQL applications.

When purchasing an ECS, you can only configure application acceleration for one type of applications.

Applicable Instances

Enabling Application Acceleration

1. Log in to the management console and access the Buy ECS page.
2. Set parameters required for creatingpurchasing ECSs.

   For details, see Purchasing an ECS in Custom Config Mode.

   To enable application acceleration, note the following settings:

   1. Set OS > Image.

      Select Public image > Huawei Cloud EulerOS > Huawei Cloud EulerOS 2.0.

   2. Select Application Acceleration.

      Select the application for which you want to configure application acceleration.

   3. (Optional) Set Security Group.
      

      If you do not use the default security group (outbound rules allow all ports by default) when purchasing an ECS, you need to perform this step to allow specific ports so that application acceleration can be available.

      Allow the following ports in the outbound rules:

      • TCP: 53, 80, and 443
      • UDP: 53
      Figure 1 Outbound rules
      
   After application acceleration is configured, the application performance is greatly improved, as shown in Table 1.

   

   The default application version in the Huawei Cloud EulerOS yum repository is installed on the ECS based on the configured application acceleration type. If you use other application versions, you may not be able to get the best performance.

   Table 1 Performance improvement

   Application	Default Version	Test Tool	Performance Improvement (Compared with No Acceleration)	Description
   Nginx	1.21.5	wrk	40% (small HTTP/HTTPS packets) 15% (large packets)	Performance improvement due to application and OS configurations are included.
   MySQL	8.0.42	sysbench	50% (OLTP read-only, write-only, and mixed read/write)
   Redis	6.2.20	memtier-benchmark	20% (small single-pipeline packets)
   PostgreSQL	13.20-1	benchmarksql	20% (read-only, write-only, and read/write)
   Memcached	1.6.12-3	memaslap	10% (small single-pipeline packets)

Checking Application Acceleration

1. Log in to the ECS.
2. Run the following command as the root user to check the status of the application.

   systemctl status <APP_Name>

   Replace <APP_Name> with the process name of the application to be accelerated, for example, nginx, redis, mysqld, postgresql, or memcached.

   If the returned status is active (running), application acceleration takes effect and the application is running properly.

Table 2 lists the listening IP addresses, ports, and official websites of applications. For details about how to use these applications, see their official websites.

If your stress test tool or client wants to connect to the applications, the inbound rules of the security group must allow the listening ports listed in Table 2. Otherwise, the application cannot be connected.

Disabling Application Acceleration

1. Log in to the ECS.
2. Run the following command as the root user to uninstall applications related to application acceleration:

   bash /opt/booster_remove.sh
