Redis data persistence
Redis data persistence stores Redis data outside volatile memory so an Azure Redis instance can rehydrate after severe node failure. In Azure Managed Redis, persistence can use RDB snapshots or AOF write logs; it improves durability but is not backup or point-in-time recovery.

Redis cache shard
A Redis cache shard is a slice of the cache. Instead of forcing every key, session, counter, and hot lookup through one Redis process, the cache can divide data across multiple shards. Each shard owns part of the keyspace, so the workload has more room and more processing capacity. For a learner, the important point is simple: sharding helps a cache grow horizontally, but it also makes key design, client compatibility, monitoring, and operational change control more important.

Redis cache SKU
A Redis cache SKU is the size and capability package you buy for the cache. It answers questions like how much memory the cache has, what performance level it can provide, which high-availability or scaling features are available, and how much it will cost. For Azure teams, SKU is not just a billing label. It is a design decision that affects latency, resilience, migration options, monitoring expectations, and whether the cache can support the application when traffic grows.

Redis eviction policy
A Redis eviction policy is the configured maxmemory rule that decides which keys are eligible for removal when Redis needs memory. Azure supports policies such as volatile-lru, allkeys-lru, random, TTL-based, LFU, and noeviction depending on Redis service, tier, and database configuration.

Redis geo-replication

Redis persistence
Redis persistence is the option that lets a Redis cache survive more than memory loss. Normal Redis is often treated as disposable because data lives in memory and can be rebuilt from a database. Persistence changes that assumption by saving snapshots or append-only changes so the cache can be restored after a serious failure. In Azure, it belongs with workload recovery planning, not routine backup exports. You still decide which data is safe to keep in Redis and which must remain in a durable database.

Redis private endpoint
A Redis private endpoint gives your application a private IP path to Redis inside an Azure virtual network. Instead of letting clients reach the cache through its public endpoint, you attach a private endpoint to a subnet and connect through Private Link. The cache remains a managed Azure service, but traffic from approved networks resolves to private address space. This is most useful when security policy, compliance rules, or network design require Redis to behave like an internal dependency rather than an internet-exposed service.

Redis clustering
Redis clustering means the cache is not one giant bucket handled by one Redis process. The keyspace is divided across multiple Redis processes, often called shards, so the service can use more memory and processing power. Applications still talk to Redis, but the client library may need to understand where keys live. Clustering is useful for scale, but it changes how developers think about multi-key commands, hot keys, testing, failover, and operational monitoring.

Integrated cache
Integrated cache controls how read-heavy Cosmos DB API for NoSQL applications reduce latency and request-unit consumption by reusing cached point reads and query results. Teams see it in azure cosmos db accounts, dedicated gateway configuration. It is not Azure Cache for Redis, a client-side memory cache, analytical store, a materialized view, or a replacement for correct partitioning; confusing them can create unexpected RU spending, stale reads. Use the term when reviewing access, monitoring, cost, recovery, or performance. It keeps architects, operators, security reviewers, and support teams focused on the same setting, resource, or behavior.

Cosmos DB integrated cache
Cosmos DB integrated cache means a dedicated gateway feature that serves cached point reads and queries without consuming request units for repeated reads. It is the practical label operators use when they decide how application data should be modeled, queried, protected, and monitored in Azure Cosmos DB. In plain English, it explains where developers, platform engineers, and support teams meet: the application wants fast data access, while the platform controls scale, cost, security, and recovery. A good glossary entry helps the team know which setting to inspect, which owner to involve, and which symptoms prove the design works.

Managed instance database
A managed instance database is a database hosted inside Azure SQL Managed Instance with managed platform operations and SQL Server compatibility features. Teams use it when a workload needs managed SQL operations while keeping instance-level features closer to SQL Server. In plain English, it gives operators a named control for database-level ownership, backup evidence, restore planning, and migration clarity within a managed instance instead of leaving the decision hidden in a portal setting, script, or deployment file. Treat it as production-ready only when the owner, dependencies, permission boundary, monitoring signal, and rollback evidence are clear.

Redis cache tier
A Redis cache tier is the broad class of cache capability, while the SKU is the exact purchasable size inside that class. The tier tells you what kind of workload the cache is meant for: simple development, production high availability, larger scale, flash-backed capacity, or a managed enterprise-style Redis deployment. For learners, tier is the decision that says what features and operating expectations are on the table before anyone argues about the exact memory size.

Index size
Index size is the Azure concept that controls capacity planning, cost control, and performance expectations for indexes stored in an Azure AI Search service. Teams see it when working with azure ai search index statistics, portal index list. It is not database file size, blob capacity, a partition count, or the number of documents alone; that distinction matters because bad assumptions create partition exhaustion, slower queries. Use the term when reviewing ownership, access, monitoring, cost, recovery, or performance. It keeps architects, operators, security reviewers, and support teams focused on the same resource, setting, or behavior.
