Enabled Or Disabled Cluster Mode For AWS For Redis

We can scale the Redis cluster using Cluster Mode for Amazon ElastiCache for Redis without affecting cluster performance. When we start a scale-out operation, we add a certain number of additional clusters to an existing cluster. When we start a scale-up or scale-down operation, we choose a new desired node type and start a new cluster that synchronizes the new nodes with the old ones.

Depending on the needs for reliability, availability, and scaling, Amazon ElastiCache for Redis supports three cluster configurations: Redis (single node), Redis (cluster mode disabled), and Redis (cluster mode enabled).

1. Redis (cluster mode enabled): The Redis cluster can now scale horizontally (in or out) in addition to vertically with Cluster Mode enabled (up and down). Redis (with cluster mode enabled) allows us to divide up to 500 node groups into partitions. As our needs vary, we can dynamically adjust the number of shards. We can construct a cluster with unexpected network and storage requirements or with a write-intensive workload by using Amazon ElastiCache for Redis with Cluster Mode enabled.

2. Redis (cluster mode disabled): We can have a replication group of up to five read replicas in a Redis cluster with cluster mode disabled.

Factors affecting the selection of Enabled or Disabled cluster mode for AWS for Redis

1. Scaling and Partitioning: Businesses must adapt. We must either scale as demand fluctuates or make provisions for peak demand. Scaling is supported by Redis (cluster mode disabled). By adding or removing replica nodes, we can increase read capacity. We can also increase capacity by scaling up to a more powerful node type. Both of these processes require time.

Redis (with cluster mode enabled) allows us to divide up to 500 node groups into partitions. As the user needs vary, we can dynamically adjust the quantity of shards. Partitioning has the benefit of distributing the load across more endpoints, which lessens access bottlenecks during periods of high demand. Since the data can be distributed over numerous servers, we can also accommodate a bigger data collection.

2. Node size and the number of nodes: The node type must be big enough to hold all the cluster’s data in addition to the necessary overhead because a Redis (cluster mode disabled) cluster only has one shard. On the other hand, when using a Redis (cluster mode enabled) cluster, the node types can be smaller even though we need more of them because we can split the data across multiple shards.

3. Read and Writes: We can scale a Redis cluster (with cluster mode disabled) by adding and removing read replicas if the majority of the load on the cluster comes from applications reading data. There are only a maximum of 5 read replicas, though.
