Serverless Redis Is Here!

We are excited to introduce Lambda Store. Lambda Store is the first Serverless Redis service. It enables developers to boost their application with Redis without paying hundreds of dollars. You can have a fully managed Redis database in seconds. Lambda Store team deals with persistence, replication, maintenance, and all other boring stuff while you focus on your application.

Lambda Store is not “yet another Redis Cloud”. Let’s talk more about what makes Lambda Store so different?

1- Serverless Pricing Model

You have a new project and you do not know how many requests will it receive? You love the performance and simplicity of Redis. But all Redis Cloud services ask charges you per instance or per GB of memory. But maybe your application will not receive any traffic in the first days, then why will you pay so much? Unfortunately, none of the current Redis cloud products provides a real pay-per-use pricing model.

Let’s do a simple calculation. Say I have a 1GB Redis database and I receive 1 million requests per month. For Elasticache (cache.t3.small, $0.034 hourly) this costs at least $24 assuming there is no data transfer and storage cost. For RedisLabs, the 1GB plan costs $22 per month. For Lambda Store the price is $0.4 per 100k requests. For 1 million, it is $4 plus the storage cost that is $0.15. So for 1GB, 1M request per months, Elasticache is $24, RedisLabs is $22, Lambda Store is $4.15

What if your product becomes so popular that it receives high and steady traffic? Most of the serverless products start to lose their spell when the application receives steady and high traffic as it starts to cost more than server/instance-based pricing models. To overcome this situation we give you the option to purchase reserved databases. A reserved database has a fixed price per month with a restriction on max throughput and data size. For high and steady throughput use cases, reserved databases cost less than serverless one. The good thing is you can start your database with serverless pricing and move it to reserved pricing when you want. See reserved plans for more information.

2- Younger Technology

Create a database in Elasticache and Redis Labs. Then create one in Lambda Store. Do you feel the difference? It takes minutes with both of them while Lambda Store database is ready in 2 seconds. Both Elasticache and Redis Labs are 9 years old technologies. It is late for them to make use of the technologies of post kubernetes era. Meanwhile, Lambda Store is a child of cloud native world. It is fully based on containers and kubernetes. This enables Lambda Store to satisfy the needs of new world of serverless.

3- Hungry Team

Elasticache is just one of the hundreds of services of AWS and you can easily say it is not one of them that AWS invests and promotes most. Redis Labs is a VC backed company and it fights with AWS to win enterprise customers. It is understandable that Redis Labs focuses more on big enterprise customers to keep its shareholders happy. Whereas, the Lambda Store team is hungry and passionate to make every user happy whoever touches Lambda Store.

What is next?

Right now, Lambda Store supports AWS. We have already started working on GCP and Azure. Moreover, we are working on more advanced database types that will have replication among availability zone to provide a higher level of availability. Currently, Lambda Store supports majority of the Redis API; but we are working on the missing ones too.

Try Out!

We will be more than happy if you try out Lambda Store and send your feedback via You can join our community Gitter channel too. Lambda Store is so easy to start but still, we prepared a Getting Started Guide.
