Amazon S3 vs Cassandra: What are the differences?
What is Amazon S3? Store and retrieve any amount of data, at any time, from anywhere on the web. Amazon Simple Storage Service provides a fully redundant data storage infrastructure for storing and retrieving any amount of data, at any time, from anywhere on the web.
What is Cassandra? A partitioned row store. Rows are organized into tables with a required primary key. Partitioning means that Cassandra can distribute your data across multiple machines in an application-transparent matter. Cassandra will automatically repartition as machines are added and removed from the cluster. Row store means that like relational databases, Cassandra organizes data by rows and columns. The Cassandra Query Language (CQL) is a close relative of SQL.
Amazon S3 can be classified as a tool in the "Cloud Storage" category, while Cassandra is grouped under "Databases".
"Reliable", "Scalable" and "Cheap" are the key factors why developers consider Amazon S3; whereas "Distributed", "High performance" and "High availability" are the primary reasons why Cassandra is favored.
Cassandra is an open source tool with 5.27K GitHub stars and 2.35K GitHub forks. Here's a link to Cassandra's open source repository on GitHub.
According to the StackShare community, Amazon S3 has a broader approval, being mentioned in 3231 company stacks & 1611 developers stacks; compared to Cassandra, which is listed in 342 company stacks and 240 developer stacks.
Hello! I have a mobile app with nearly 100k MAU, and I want to add a cloud file storage service to my app.
My app will allow users to store their image, video, and audio files and retrieve them to their device when necessary.
I have already decided to use PHP & Laravel as my backend, and I use Contabo VPS. Now, I need an object storage service for my app, and my options are:
Amazon S3 : It sounds to me like the best option but the most expensive. Closest to my users (MENA Region) for other services, I will have to go to Europe. Not sure how important this is?
DigitalOcean Spaces : Seems like my best option for price/service, but I am still not sure
Wasabi: the best price (6 USD/MONTH/TB) and free bandwidth, but I am not sure if it fits my needs as I want to allow my users to preview audio and video files. They don't recommend their service for streaming videos.
Backblaze B2 Cloud Storage: Good price but not sure about them.
There is also the self-hosted s3 compatible option, but I am not sure about that.
Any thoughts will be helpful. Also, if you think I should post in a different sub, please tell me.
If pricing is the issue i'd suggest you use digital ocean, but if its not use amazon was digital oceans API is s3 compatible
The problem I have is - we need to process & change(update/insert) 55M Data every 2 min and this updated data to be available for Rest API for Filtering / Selection. Response time for Rest API should be less than 1 sec.
The most important factors for me are processing and storing time of 2 min. There need to be 2 views of Data One is for Selection & 2. Changed data.
CassandraCassandra is quite capable of the task, in a highly available way, given appropriate scaling of the system. Remember that updates are only inserts, and that efficient retrieval is only by key (which can be a complex key). Talking of keys, make sure that the keys are well distributed.
ScyllaScylla can handle 1M/s events with a simple data model quite easily. The api to query is CQL, we have REST api but that's for control/monitoring
ScyllaBy 55M do you mean 55 million entity changes per 2 minutes? It is relatively high, means almost 460k per second. If I had to choose between Scylla or Cassandra, I would opt for Scylla as it is promising better performance for simple operations. However, maybe it would be worth to consider yet another alternative technology. Take into consideration required consistency, reliability and high availability and you may realize that there are more suitable once. Rest API should not be the main driver, because you can always develop the API yourself, if not supported by given technology.
Cassandrai love syclla for pet projects however it's license which is based on server model is an issue. thus i recommend cassandra
Minio is a free and open source object storage system. It can be self-hosted and is S3 compatible. During the early stage it would save cost and allow us to move to a different object storage when we scale up. It is also fast and easy to set up. This is very useful during development since it can be run on localhost.
We offer our customer HIPAA compliant storage. After analyzing the market, we decided to go with Google Storage. The Nodejs API is ok, still not ES6 and can be very confusing to use. For each new customer, we created a different bucket so they can have individual data and not have to worry about data loss. After 1000+ customers we started seeing many problems with the creation of new buckets, with saving or retrieving a new file. Many false positive: the Promise returned ok, but in reality, it failed.
That's why we switched to S3 that just works.
