ElastiCache Pricing in India 2026: Mumbai Costs in Rupees

· · 8 min read

ElastiCache pricing in India, Mumbai region costs in rupees for nodes, serverless, replicas and GST

ElastiCache pricing looks simple on the AWS page and gets confusing the moment you try to work out a monthly bill in rupees. This guide is for developers and founders in India pricing a managed Redis or Valkey cache on AWS. Every number below comes from AWS’s own published price list for the Mumbai region (ap-south-1), dated 28 October 2026, converted to rupees at a stated rate, with the parts that change the bill most: which engine you pick, serverless minimums, replicas and GST.

How ElastiCache charges

There are two ways to buy it:

  1. Node-based (self-designed) clusters. You pick an instance size and pay for every hour each node runs, whether it is busy or idle. A replica for failover is another node at the same price.
  2. Serverless. No sizes to pick. You pay for the data you store, per GB-hour, plus the requests you send, in ElastiCache Processing Units (ECPUs). Each cache has a minimum amount of data you are billed for, even if you store less.

Backup storage beyond the free allowance, and data sent between Availability Zones or out of AWS, are billed separately.

How we converted. AWS publishes Mumbai prices in US dollars. We multiplied by 730 hours for a month and converted at Rs 93.92 per dollar, the European Central Bank reference rate for 6 November 2026. If your account is billed by AWS India, your invoice is in rupees at AWS’s own rate and adds 18% GST, so treat the rupee figures as close estimates before GST. The dollar prices are exact, from the ElastiCache pricing page and AWS’s price list file.

Node prices in Mumbai, in rupees

On-demand, per node, Mumbai region, before GST.

Node Memory Valkey per hour Valkey per month Redis OSS per hour Redis OSS per month
cache.t4g.micro 0.5 GiB $0.0160 about Rs 1,097 $0.0200 about Rs 1,371
cache.t4g.small 1.37 GiB $0.0328 about Rs 2,249 $0.0410 about Rs 2,811
cache.t4g.medium 3.09 GiB $0.0648 about Rs 4,443 $0.0810 about Rs 5,553
cache.m7g.large 6.38 GiB $0.1312 about Rs 8,995 $0.1640 about Rs 11,244
cache.r7g.large 13.07 GiB $0.1792 about Rs 12,286 $0.2240 about Rs 15,358

Two things to know about these sizes. The memory figure is the whole node, and part of it is needed by the engine itself and for background saves, so plan to fill no more than about three-quarters of it. And the t4g sizes are burstable: they suit steady light traffic, not sustained heavy load.

Bar chart: monthly cost in rupees in the Mumbai region for one node, Valkey compared with Redis OSS - t4g.micro about 1,097 vs 1,371, t4g.small 2,249 vs 2,811, t4g.medium 4,443 vs 5,553, m7g.large 8,995 vs 11,244, r7g.large 12,286 vs 15,358

Serverless: the minimum decides small bills

Mumbai, serverless Valkey Redis OSS
Data stored, per GB-hour $0.054 $0.081
Requests, per million ECPUs $0.0015 $0.0022
Minimum data billed per cache 100 MB 1 GB
Minimum per month, from data alone about $3.94 (about Rs 370) about $59.13 (about Rs 5,553)

For a small app this table is the whole story. A Redis OSS serverless cache costs at least about Rs 5,553 per month before GST even if it holds one key, because you pay for 1 GB regardless. The same cache on Valkey starts at about Rs 370. Requests are cheap at small scale: 100 million ECPUs cost about $0.15 on Valkey.

Above the minimum, serverless costs about $39.42 (about Rs 3,702) per GB stored per month on Valkey. A cache that holds more than a few GB around the clock is usually cheaper on nodes; one that is small or spiky is usually cheaper serverless.

Valkey or Redis OSS: the same cache, a different price

On every line above, Valkey is cheaper: 20% less on nodes, 33% less on serverless storage and 32% less on requests, and a minimum one-tenth the size. Both speak the same protocol, so your client library does not change.

The reasons to stay on Redis OSS are narrow: data files from Redis 7.4 or later that you need to load directly, or features that exist only in newer Redis releases. We covered the differences, with a benchmark, in Valkey vs Redis. For most caches on AWS today, Valkey is the default choice on price alone.

What a real setup costs

Three common shapes, Mumbai, Valkey, before GST:

Setup What you run About per month
Side project or staging 1 x cache.t4g.micro, no replica Rs 1,097
Production cache with failover 1 primary + 1 replica, cache.t4g.small Rs 4,498
Busy app, 1 primary + 1 replica cache.m7g.large x 2 Rs 17,991

Add 18% GST on an AWS India invoice. A replica doubles the node cost, and with Multi-AZ automatic failover turned on it takes over when the primary fails; without one, a node failure means downtime and an empty cache.

The costs that are not on the price card

  • Reaching it from outside AWS. ElastiCache is reached from inside your AWS network (VPC). If your app runs somewhere else, you need extra networking, and its cost and latency, to connect at all.
  • Data transfer. Traffic between your app and the cache in the same Availability Zone is free; traffic across zones is billed per GB in each direction. A replica in another zone, or an app spread across zones, adds to it.
  • Backups. Snapshots beyond the free allowance cost $0.085 per GB-month in Mumbai.
  • Your time. Sizing nodes, setting parameter groups, VPC security rules and upgrade windows are yours to manage on the node-based option.

Is there a free tier?

New AWS accounts created since 15 July 2025 get credits rather than a permanent free cache: $100 at sign-up and up to $100 more, which AWS says can be used towards ElastiCache, for up to 6 months, with a card required. After that you pay the prices above. For a free cache with no end date, our free Redis hosting comparison lists eight options and the catch in each.

Alternatives priced in rupees

If your app does not run on AWS, or you want a bill in rupees with no conversion, a managed store outside AWS can be simpler. For comparison, Voroa’s key value sizes, set in rupees and billed with a GST invoice:

Voroa key value size Memory CPU (shared) Price before GST
Cache Nano (free) 128 MB 0.05 Rs 0
Cache Nano Plus 128 MB 0.1 Rs 249 per month
Cache Starter 256 MB 0.1 Rs 425 per month
Cache Standard 1 GB 0.25 Rs 1,349 per month
Cache Standard Plus 3 GB 0.5 Rs 3,499 per month
Cache Pro 5 GB 0.5 Rs 5,699 per month
Cache Pro Plus 10 GB 2 Rs 10,499 per month

The same caution as for ElastiCache applies, more strongly: the memory figure is the whole instance, and Voroa can hold back up to 40% of it for the nightly save, so a 1 GB store may hold about 600 MB of data. Compare usable data, not the label, when you weigh the two.

These are single instances with data written to disk and a nightly snapshot, not a primary-plus-replica cluster, so compare them with a single ElastiCache node rather than a failover pair. They run in Mumbai next to the web services you deploy, reached over a private network. The full details are on the managed Redis page and in the Key Value guide. Our Redis job queue guide explains why a queue needs a store that does not evict keys, which matters whichever host you choose.

FAQ

How much does ElastiCache cost per month in India? The smallest Mumbai node, cache.t4g.micro on Valkey, is about Rs 1,097 per month before GST. A serverless Valkey cache starts at about Rs 370 per month. A production pair with failover on cache.t4g.small is about Rs 4,498.

Is ElastiCache Valkey cheaper than Redis? Yes. In Mumbai, Valkey nodes cost 20% less, serverless storage 33% less and requests 32% less, and the serverless minimum is 100 MB instead of 1 GB.

Does ElastiCache charge GST in India? Accounts billed by AWS India are invoiced in rupees with 18% GST added.

Is ElastiCache serverless cheaper than nodes? For small or spiky caches, usually yes, especially on Valkey. For a cache holding several GB all day, nodes are usually cheaper.

Can I connect to ElastiCache from outside AWS? Not directly. It is reached from inside your AWS network, so an app hosted elsewhere needs extra networking to connect.

Is there an ElastiCache free tier in 2026? New accounts get up to $200 in AWS credits for up to 6 months instead of a permanent free tier.
