TencentDB for MongoDB

A stable, secure, high-performance document database for any business scale

Overview

TencentDB for MongoDB is a high-performance NoSQL database built by Tencent Cloud based on MongoDB, a globally popular database program. Fully compatible with the MongoDB protocol, it provides stable and rich features for monitoring management, elastic scaling and automatic disaster recovery, making it ideal for document database scenarios and eliminating the need for self-built disaster recovery and control management systems.

Benefits

High Performance

Fitted with an ultra-large memory, brand-new PCI-E SSD storage media, next-gen storage engine and optimized native Mongo kernel, TencentDB for MongoDB can process 30,000+ queries per second (QPS), helping sustain massive volumes of concurrent requests during peak business hours. Furthermore, it eliminates the need to design complex backend systems for processing high numbers of requests, greatly simplifying your system development process.

Distributed Cluster Construction

Compatible with most native protocols, Tencent's proprietary distributed MongoDB cluster stores data on multiple physical servers through shard keys, enabling unlimited storage capacity and load distribution. One-click cluster creation and capacity expansion significantly improves the efficiency of building massive distributed storage systems. 

Complete Data Protection Mechanism

With a complete automatic data backup and lossless recovery mechanism, each instance cluster is backed up once a day by default, while dual-server hot backup is performed in real time for the nodes in the cluster. This completely eliminates the concerns over data loss and saves the extra investment required for ensuring high data reliability. Data encryption service is available for another layer of security protection.

Integrated Monitoring

Monitoring is available in three dimensional metrics including single instance, primary node and secondary node as well as professional data metrics such as disk usage, CPU load and QPS. The operational data are visualized for clear display.

Professional OPS Service

Instance deployment, version updates and troubleshooting are well taken care of by the TencentDB team. The master/slave switchover, troubleshooting and data migration are completely imperceptible, and the IP and port remain unchanged. Without the need to worry about IP drift for your applications, OPS costs are greatly reduced.

Elastic Capacity Expansion

When the available storage capacity is insufficient, the capacity can be expanded online via the console. The expansion process does not affect your online businesses and can be done conveniently and quickly with one click in the console, eliminating the need to care about the underlying implementation details.

High Service Availability

Dual-server hot backup and multiple fault detection mechanisms ensure that the service is automatically switched to the slave server in a matter of seconds in case of failure with the master server. No operations are required on your end and there is no impact on your online businesses. High service availability is ensured with no additional development of related systems required.

Custom Alarming

The custom alarming feature is available for resource thresholds to help detect operational issues of MongoDB. It promptly notifies OPS personnel of the issues, enabling them to respond quickly to database problems.

Features

TencentDB for MongoDB provides a high-performance, secure and stable cloud document database service. Elastically scalable instances can be created and scaled with one click, making them simple, convenient and easy to use. The system provides enterprise-grade monitoring service to ensure your business stability and continuity.

Compatible with most native protocols, Tencent's proprietary sharding MongoDB cluster stores data on multiple physical servers through shard keys, enabling unlimited storage capacity and load distribution.

Scenarios

Internet of Things

Terminal devices in the Internet of Things (IoT) industry such as medical instruments and vehicle GPS receivers can easily and continuously generate terabytes of data. The sharding technology of TencentDB for MongoDB enables you to build a distributed database cluster with ease to achieve unlimited storage capacity and facilitate online expansion. The native map-reduce aggregation framework can help you tap into the hidden value of such massive amounts of data.

Game Development

Gaming needs shift rapidly. TencentDB for MongoDB is especially ideal for use as backend gaming database. Its schema-free mode eliminates the pain of changing the table structure and greatly shortens the version iteration cycle, saving up to 60% of development time. It can also be used as a cache server to schedule hot data properly. Its performance is comparable to that of other popular cache servers, and it features a wider variety of query methods.

Read-write Separation

For many applications that are not particularly demanding on data timeliness, read-write separation can be achieved by purchasing one or more read-only instances of the TencentDB for MongoDB master instance. Read operations can be performed in the read-only instances to meet the needs of high-volume read applications , reducing the pressure on the main database. All write requests are distributed to the primary node, and data is automatically synced between the master instance and the read-only instances.

Pricing

TencentDB for MongoDB is pay-as-you-go, making it very suitable for businesses with needs that can fluctuate instantaneously. This billing method is recommended for users with high and unpredictable fluctuations in business development or temporary and sudden resource requirements. Pay-as-you-go is a postpay billing method. When you create a document database, we will freeze the hardware cost of one hour in your Tencent Cloud account and charge the usage fee on the dot of each hour (Beijing time). The billing time is accurate down to the second. With the pay-as-you-go billing method, you only need to pay for what you use, and no upfront payment is required. View more>>
