Challenges & Goals

As a SaaS platform, Posify requires a powerful cloud architecture in addition to software architecture to support its sustainable development. The efficiency, scalability, and stability of the cloud architecture, network security, and real-time support all deserve careful consideration in order to deliver an enterprise-grade SaaS experience for its customers.

Why Tencent Cloud

Posify mainly uses the following Tencent Cloud services:

1. Database

Posify has opted for TencentDB for MariaDB and TencentDB for Redis. As the main database for online transaction processing (OLTP), TencentDB for MariaDB adopts the architecture of one primary node (read-write) and two secondary nodes (read-only) and boasts automatic backup, rollback, and other features, helping Posify improve its system performance and availability. The distributed cache technology of TencentDB for Redis is also fully leveraged.

TencentDB for Redis enables Posify to design and process business logics for different use cases. For example, during online flash sales, Posify can use TencentDB for Redis instances as a buffer to reduce the read/write loads of databases and prevent access delay or failure due to traffic surge.

2. Logical application layer

The logical application layer consists of system server APIs, through which online store entries, APIs, backend entries, and reports are handled. To meet the diverse needs of merchants, a combination of independent Cloud Virtual Machine (CVM) and Auto Scaling (AS) instances is adopted for Posify's each type of server, which, along with Cloud Load Balancer (CLB), can achieve automatic traffic distribution and automatic configuration adjustment based on traffic. This helps Posify improve its system availability and save costs.

3. Network connection

In addition to CLB, Posify also uses Content Delivery Network (CDN) to deliver static content needed by online stores, such as images, CSS code, and JS code. This speeds up file downloads and responds faster for a smoother user experience.

4. Network security

All Tencent Cloud services are under protection by multiple layers of firewalls. Only ports required by specific services are open to isolate risky operations. To strengthen network security, Posify uses Anti-DDoS to prevent service unavailability due to high-traffic DDoS attacks.

Highlighted Benefits

Thanks to Tencent Cloud, Posify is not only better equipped to address various challenges in cloud infrastructure, but also sees significant improvements in efficiency, scalability, stability, network security, and support services. It has received a lot of positive customer feedback about the speed increase after migration to Tencent Cloud.

Tencent Cloud has been playing an essential role in Posify's business expansion. Tencent Cloud's highly efficient and secure cloud services follow strict information security policies to prevent attacks. Furthermore, the services are highly flexible, making it easier to scale anytime as needed. More importantly, Tencent Cloud's technical team provides professional opinions and support for Posify to underpin its rapid development.
