Scenario

The customer has typical multi-layer WEB applications, including WEB servers and database servers. The WEB server and database server must be isolated because the WEB server is used to provide external services and the database server is used to provide internal services.

Pain Points

In addition, the database server does not allow external access. WEB server and database server must be isolated.

Advantages

The WEB server and database server can be configured on different subnets in the same VPC. The WEB server can be connected to the Internet, and the database server can be set to only access the Intranet, ensuring database server security.
You can configure security groups and ACLs to prevent external hosts from accessing the database to ensure database server security.
Services are allocated to multiple ECS through LB to enhance service processing capabilities.
It seamlessly integrates with AS to ensure stable and reliable operation of business in case of massive access requests. It automatically scales up the capacity based on traffic to cope with workload spikes.

Recommended combination for use

Elastic Load Balancing

Scenario

Based on eSurfing Cloud VPC, a cloud-based data center can be built and connected with the internal enterprise data center off the cloud through CDA or VPN. A communication tunnel is established between the enterprise data center and the private network in VPC, making it convenient to use ECSs and storage resources, and constructing hybrid cloud architecture. In this way, it could perfectly cope with the surge in business and rapid data synchronization at a lower IT O&M cost while blocking the proliferation of core data.

Pain Points

Users are worried about migration to the cloud because their business is running and their data is stored off the cloud. The business data of enterprise users is increasing rapidly, but it is time-consuming and expensive for a data center off the cloud to scale up its capacity. In this case, real-time AS is needed. Enterprises worry that the cloud configuration is complicated and time-consuming, which may affect their business.

Advantages

CDA or VPN is used to migrate business to the cloud to build a hybrid cloud while enterprise data can be saved off the cloud to minimize potential security threats.
Online and as-per-use AS of computing power and network bandwidth can reduce the cost and shorten the time.
Graphical modular configuration simplifies the networking plan and improves its flexibility, and the business can be migrated through online configuration.

Recommended combination for use

Cloud Dedicated Access

Scenario

An exclusive cloud-based private network environment built based on the eSurfing Cloud is completely isolated from other tenants to ensure service security. Subnets are set up in different availability zones to enable cross-AZ business DR.

Pain Points

The business of a customer must be completely isolated from other customers to ensure business security. DR must be performed on customer business to avoid interruption due to single-server downtime.

Advantages

Relying on the tunnel technology, it isolates different VPCs from one another completely to ensure that customer business are deployed on dedicated private networks, so as to ensure the security and reliability of the business.
The high availability architecture of the eSurfing Cloud with multiple availability zones enables customers to deploy their business in clusters across different availability zones, avoiding business interruption caused by the failure of a single IDC room.
