+<p id="CacheSingleNode__p188211915114319">In summary, single-node DCS instances support highly concurrent read/write operations, but do not support data persistence. Data will be deleted after instances are restarted. They are suitable for scenarios which do not require data persistence, such as database front-end caching, to accelerate access and ease the concurrency load off the backend. If the desired data does not exist in the cache, requests will go to the database. When restarting the service or the DCS instance, you can pre-generate cache data from the disk database to relieve pressure on the backend during startup.</p>

Generally, updates to the master cache node are automatically and <span class="keyword" id="dcs-faq-0730061__keyword345415235102">asynchronously replicated</span> to the standby cache node. This means that data in the standby cache node may not always be consistent with data in the master cache node. The inconsistency is typically seen when the I/O write speed of the master node is faster than the synchronization speed of the standby node or a network latency occurs between the master and standby nodes. If a failover happens when some data is not yet replicated to the standby node, such data may be lost after the failover.</p>

In such scenarios, you can use Redis to achieve fast yet inexpensive access to data. Redis enables you to retrieve data from in-memory data stores instead of relying entirely on slower disk-based databases. In addition, you no longer need to perform additional management tasks. These features make Redis an important supplement to traditional disk-based databases and a basic service essential for internet applications receiving high-concurrency access.</p>
+<p id="dcs-pd-0326002__en-us_topic_0145956241_p105920376415">Typical application scenarios of DCS for Redis are as follows:</p>

+<p id="dcs-pd-0326002__en-us_topic_0145956241_p379443010317">For example, the high-concurrency data access in flash sales can be hardly handled by traditional relational databases. It requires the hardware to have higher configuration such as disk I/O. By contrast, Redis supports 100,000 QPS per node and allows you to implement locking using simple commands such as <strong id="dcs-pd-0326002__b990545219496">SET</strong>, <strong id="dcs-pd-0326002__b1907115220497">GET</strong>, <strong id="dcs-pd-0326002__b1590775224912">DEL</strong>, and <strong id="dcs-pd-0326002__b69072525492">RPUSH</strong> to handle flash sales.</p>

IAM provides identity authentication, permissions management, and access control, helping you secure access to your resources.</p>
+<p id="dcs-pd-210626001__en-us_topic_0170871404_p57386149361">With IAM, you can use your account to create IAM users, and assign permissions to the users to control their access to specific resources. For example, some software developers in your enterprise need to use DCS resources but should not be allowed to delete DCS instances or perform any other high-risk operations. In this scenario, you can create IAM users for the software developers and grant them only the permissions required for using DCS resources.</p>

This mechanism provides only a limited number of service-level roles for authorization. When using roles to grant permissions, you must also assign other roles on which the permissions depend to take effect.

This mechanism allows for more flexible policy-based authorization, meeting requirements for secure access control. For example, you can grant DCS users only the permissions for operating DCS instances. Fine-grained policies are based on APIs. The minimum granularity of a policy is API actions.
