Prons and Cons of Cosmos Db **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Hospital & Health Care | Mid-Market (51-1000 emp.) **Reviewed Date:** January 12, 2021 **What do you like best about Azure Cosmos DB?** The reading and writing of data is so faster than SQL. No schema makes the work easy and you need not worry about the data type all you need is model your data properly. Do the data indexing automatically so all the cluster and non cluster things are just a words to it. High availability. Globally distributed and you have one write and many read regions. Use of query and syntax, don't worry about the query syntax its very simple if you know sql query already that's is more than enough. May be the joins quite different but its easy to use. **What do you dislike about Azure Cosmos DB?** Hmm cosmos db also has its own downside. Data redundancy. Data search is quite time taken if you not properly mention the partition key and or synthetic key. Cosmos is case sensitive so store your searchable data either lower or upper, to search and retrieve quickly. Using functions like Upper and lower in queries when you have large volume of data make you feel bad. **Recommendations to others considering Azure Cosmos DB:** If you worried about indexing, scaling, expect quick read and write. Cosmos is best one. Before moving to cosmos model your data properly, partition and synthetic key since cosmos has no schema. **What problems is Azure Cosmos DB solving and how is that benefiting you?** Read and write. In MS SQL we facing issues in reading and writing data, if the data volume is high and we have to de-normalize lot of tables to avoid redundancy and that leads performance issue. Slow querying time. Global distribution and scaling. ### 14. Azure is awesome **Rating:** 5.0/5.0 stars **Reviewed by:** RajasekharReddy B. | SQL Server DBA/ Azure DBA/ Architect, Enterprise (> 1000 emp.) **Reviewed Date:** June 14, 2022 **What do you like best about Azure Cosmos DB?** Cost is very less comparatively with cloud technologies. UI is Good **What do you dislike about Azure Cosmos DB?** DB servers won't respond sometimes. More stability required **What problems is Azure Cosmos DB solving and how is that benefiting you?** It saves time to set up servers. And saves time to take ### 15. Understanding of azure services **Rating:** 4.0/5.0 stars **Reviewed by:** Swapnil D. | Associate Consultant, Enterprise (> 1000 emp.) **Reviewed Date:** June 14, 2022 **What do you like best about Azure Cosmos DB?** Microsoft Azure provides bunch of managed services for Database. Currently working on databases only **What do you dislike about Azure Cosmos DB?** Nothing.The Microsoft Azure documentation is upto date and very helpful when working on it. **Recommendations to others considering Azure Cosmos DB:** Yes **What problems is Azure Cosmos DB solving and how is that benefiting you?** I am designing the end to end solution using azure managed services which includes azure cosmos DB. ### 16. Cosmos, a good DB if you need single-collections per project. **Rating:** 3.5/5.0 stars **Reviewed by:** Cesar Daniel Z. | Senior Angular Developer, Small-Business (50 or fewer emp.) **Reviewed Date:** August 11, 2021 **What do you like best about Azure Cosmos DB?** CosmosDB is really fast and easy to track the items since it's a simple JSON that you can manipulate in any language or use any format you want (obviously that is JSON valid), so that is really useful if you're developing microservices for example. Also, it has a web-based editor where you can run queries pretty easy to find certain information, so at the end it's: Fast Easy to use And it's perfect for a single-table service **What do you dislike about Azure Cosmos DB?** 5 things make Cosmos a "not-so-good" pick for a database (even when we talk about NoSQL DBs): 1.-It's hard to create a paginated service, most of the time we don't want to show all the records, and just a few per page to make it easy for the front to show that information, Cosmos is not the best pick for this. 2.-The libraries are not the best for the usage, at least in Node, is pretty bad 3.-The documentation is not that clear or good (at least I can't find too much information on how to use it) 4.-You can't delete in bulk, for example, so you need to create a stored procedure that is at the end code, which then, removes 1 by 1... 5.-I know that this is a NoSQL DB, so, there are no relations between collections/tables, but, you need to create multiple connections per collection/container (at least in Node) and then use each instead of opening a general connection that allows us to use any collection inside, and based on the `SELECT * FROM c` you should be able to set "c" as a specific collection like in "SQL" or at least, set the collection you want to use in a single connection but you can't and need to initialize multiple connections So, because of those options, I would not use it in a multi-table service **Recommendations to others considering Azure Cosmos DB:** If you are going to create a CRUD, don't use it, if you're going to use it like for "settings", single-services, microservices that runs on 1 table only, or something similar, then, go ahead, Cosmos ir your choose above Mongo or others :) **What problems is Azure Cosmos DB solving and how is that benefiting you?** We are developing a Twilio IVR bot with Bot Framework, so, we needed a way to keep "the state" of the conversation flow, first we used files, and it was really bad, because it started to create tons of files in the Twilio Cloud Functions, and it became a horror to track anything, and since we were not able to keep multiple calls from the same phone number, we had to remove the files, so at the end, we were not able to check any internal info that we could gather and used the Twilio Debugger instead. So, we decided to go with a NoSQL database, and we choose Cosmos instead of Mongo or other NoSQL DBs because of the reasons I said before, it was really fast, easy to use for this single-table service and we could share it with our other single-table services that were running in Azure cloud. In the end, it is working really amazing, with pretty good SLA, speed, and we can pull some info using the web interface really easy (even with the other things I don't like, I think it was a good option to choose it) ### 17. Fully managed database service **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Retail | Mid-Market (51-1000 emp.) **Reviewed Date:** December 06, 2021 **What do you like best about Azure Cosmos DB?** Azure Cosmos DB supports multiple services like SQL, NoSQL, GRAPH. Azure Cosmos Db uses gremlin for the graph service. It provides multi-region scalability, 99.99 % uptime in the SLA. The pricing is based o RUs(Request Units), so it means we pay on the usage of it. **What do you dislike about Azure Cosmos DB?** Though it's pretty scalable and supports enterprise business, it comes at a very high cost. The cost is in terms of RUs, and it's pretty expensive than other managed services. **What problems is Azure Cosmos DB solving and how is that benefiting you?** We are storing products data, customers information in Azure Cosmos DB in the SQL service. Most of the APIs are using it to fetch relevant data and information to render it to the client. ### 18. Flat NoSql db **Rating:** 4.5/5.0 stars **Reviewed by:** VIPIN Y. | Software Developer, Mid-Market (51-1000 emp.) **Reviewed Date:** August 11, 2021 **What do you like best about Azure Cosmos DB?** You can read and insert data very easily in the Azure Cosmos DB. It is a NoSQL Database there is no schema. Means no need to use join complex queries. **What do you dislike about Azure Cosmos DB?** Nothing. But if you have a lot of documents in a collection and you don't know about partition Key . Then it will take much time to return the data. **What problems is Azure Cosmos DB solving and how is that benefiting you?** Earlier I was using Mysql DB. That was the relational database. For getting Some data I feel very complex in the join operation. But Cosmos DB helps me to avoid these complexities. ### 19. Simple, Fast & most Powerful DB **Rating:** 5.0/5.0 stars **Reviewed by:** Sathish K. | Senior Consultant, Mid-Market (51-1000 emp.) **Reviewed Date:** January 18, 2021 **What do you like best about Azure Cosmos DB?** 1.The first and at most admire thing from Cosmos DB for me it is a Non structured (No-SQL) Database. 2. You can store any data's in the format for JSON, by simply differentiate with partition key's. 3. And it's very easy to configure on go. 4.I would must mention this, since this DB values are storing in JSON format it was very fast to access the large no of data's for all the CRUD operations. 5.It allows the API call's to perform the CRUD operations over in COSMOS DB with the help of SQL, Mongo DB, Cassandra, and Gremlin Api's. 6.There is other interesting feature is whenever the COMOS DB Perform actions you can get the Trigger point and perform other options well. For ex on Create of data in Comos DB or delete or Update of Comos DB values you can get the Trigger point and perfrom other actions with the help of Change feed and Function app's. **What do you dislike about Azure Cosmos DB?** 1. Im a huge fan of comos db and i dont have any negative points on it. **What problems is Azure Cosmos DB solving and how is that benefiting you?** 1. We were implementing the Comos DB as a centralized data warehouse to sync the data between all other integrated systems. Since the DB is stable and actions are so fast we were using it as data hub. ### 20. Optimized database service to meet all the modern time demands and requirements **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer & Network Security | Enterprise (> 1000 emp.) **Reviewed Date:** July 24, 2021 **What do you like best about Azure Cosmos DB?** It is a really, very fast database service, and it can store a large chunk of data.

Excellent NoSQL Database but Pricey **Rating:** 3.5/5.0 stars **Reviewed by:** Grant A. | Mid-Market (51-1000 emp.) **Reviewed Date:** July 28, 2020 **What do you like best about Azure Cosmos DB?** Azure Cosmos DB is a fully managed NoSQL database based upon MongoDB. It is an excellent and easy to use NoSQL database. **What do you dislike about Azure Cosmos DB?** Pricey! And throttled. Throttled means that if your query consumes too many resources then it's going to be throttled, i.e. delayed, some...Sometimes a lot! You won't find this a problem with small databases but when they get bigger and you need to do some queries on them for such things as reporting then you're going to hit your head against this glass ceiling. The solution is to patiently wait...Or to move to a higher pricing tier where the throttling is much less. You cannot run Cosmos DB on your own VM...But you can run MongoDB on your own VM. Much, much cheaper! And no throttling! **What problems is Azure Cosmos DB solving and how is that benefiting you?** Storage of records/documents from a .NET microservice. Works very well! But is quite expensive! ### 22.

Azure Cosmos DB **Rating:** 4.0/5.0 stars **Reviewed by:** Vaibhav S. | Software Engineering Intern, Computer & Network Security, Small-Business (50 or fewer emp.) **Reviewed Date:** September 23, 2018 **What do you like best about Azure Cosmos DB?** CosmosDB allows you to select an API (eg, MongoDB) during initialization. It comes in very handy if you need to save some time and skip the documentation (not the case with other databases) **What do you dislike about Azure Cosmos DB?** Due to the limitations of your Azure plan, it is possible that CosmosDB will not let you aggregate over larger records. I faced this issue ( probably because of my plan). **What problems is Azure Cosmos DB solving and how is that benefiting you?** IoT data storage and retrieval. CosmosDB really helped me to store the data points in a schema as soon as the RPI's sent them to IoT Hub ### 39. Document DB - A mixed strength of both NoSQL and relational solutions **Rating:** 5.0/5.0 stars **Reviewed by:** Sujith N. | Technology Analyst, Information Technology and Services, Enterprise (> 1000 emp.) **Reviewed Date:** January 25, 2018 **What do you like best about Azure Cosmos DB?** 1. Documents are stored and served in the JSON format 2. Documents can be retrieved using a rich query language that plays well with the JSON syntax 3. It has a rich server-side Javascript API, letting you create data processing functions 4. full indexing is done by default hence query performance would be better 5. Comparatively cheaper to other No SQL DB's **What do you dislike about Azure Cosmos DB?** 1. DocumentDB cannot enforce or guarantee data consistency like SQL can 2. DocumentDB queries are much more limited than SQL queries. 3. The Portal seems a little less user friendly for accessing the doc db collections **Recommendations to others considering Azure Cosmos DB:** There are certain points to be noted while selecting this product for our application 1. Price - What kind of usage is applicable for us and based on that we need to select the collections and structure of the documents created in it 2. Write Once - Read Many - This is a write once and read many kind of DB where we do only once write and then later perform search on this 3. Full Indexing is there by default, still we can bring custom indexing policy if required **What problems is Azure Cosmos DB solving and how is that benefiting you?** Application which is used for staffing and recruitment. In our application we track the order audit details in doc db for easy accessibility. ### 40. While scalability, price and "every field index" is attractive cosmos db has some problems **Rating:** 3.0/5.0 stars **Reviewed by:** Alon N. | Senior fullstack developer, Information Services, Small-Business (50 or fewer emp.) **Reviewed Date:** January 18, 2018 **What do you like best about Azure Cosmos DB?** Auto indexing, without noticeable performance hit, on all fields (compare to mongo ..) Global Scale without needing to reason about that, moving plans, etc Quite simple to setup with the azure cli **What do you dislike about Azure Cosmos DB?** Not really implementing all features of mongo api, at least not by default. for example, for cursor support you need to open a support ticket, for aggregations, you need to turn on a UI flag, etc. Although multiple apis, you can't actually use that in the same account (like writing with the mongo Api and doing complex queries with the sql api) Some Docs , including lib docs, are old and misleading. Like everything else azure, still the feeling that linux is "second rate citizen" in azure, some tools are missing if you are not running windows **Recommendations to others considering Azure Cosmos DB:** The different apis have meaning! you'll be locked to the one you choose. For migrating data you can configure higher request unit per second, and the lower it to a reasonable amount **What problems is Azure Cosmos DB solving and how is that benefiting you?** Datasource for setting up azure search, Simple "in place" mongo replacement for various mongo db installations ### 41. Cloud based NoSQL offering by microsoft based on mongoDB and integrated very well with Azure **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Computer Software | Enterprise (> 1000 emp.) **Reviewed Date:** April 18, 2018 **What do you like best about Azure Cosmos DB?** Security is very good. DB is protected from almost all type of attacks like DDOS, Illegal access, man in the middle. Encryption is top notch, Compliance with various regulatory authorities and governing bodies. Performance is also very good. Geographically distributed and replicated hence it offers low latency. The user can pay for access hence storage is almost free. Audit and security reports are easy to generate. Fine-grained access is also available. **What do you dislike about Azure Cosmos DB?** Cost is a bit on the higher side. Not fully flexible like other opensource offerings like Cassandra, MongoDB. Requires steep learning curve if you are not familiar with Microsoft stack. **Recommendations to others considering Azure Cosmos DB:** If you are an existing customer/partner of Microsoft and you or your team is familiar with Azure Cloud offering then is a good upgrade. **What problems is Azure Cosmos DB solving and how is that benefiting you?** Backend storage for web applications built on MEAN stack and MVC architecture. ### 42. Good Value but somewhat combersome **Rating:** 3.5/5.0 stars **Reviewed by:** Ben J. | Application developer, Mid-Market (51-1000 emp.) **Reviewed Date:** April 24, 2018 **What do you like best about Azure Cosmos DB?** Azure has done a great job at abstracting away the tedious db management. The ability to quickly spin up additional environments for testing and spin down as needed is pretty seamless. **What do you dislike about Azure Cosmos DB?** Modifications and customizations at the base level are hard to accomplish, administrative rights are (can be) IP locked. Using the platform itself is difficult. **Recommendations to others considering Azure Cosmos DB:** If you're a centralized shop or you have a db management need that you don't want to take on in house, this is a great solution. **What problems is Azure Cosmos DB solving and how is that benefiting you?** This is a great db repository that is is quickly set up and easily used for quick storage. We used this for our software development environment as a quick and local repository for dev efforts without having to fully commit to our own infrastructure. We do not currently have an instance created. ### 43.

It was very easy to get an account open and have our data uploaded and be fetched and manipulated by the app we designed **What do you dislike about Azure Cosmos DB?** The Cost, as in we had a very small dataset hosted on cosmos DB but still, it incurred substantial cost for just keeping the service on the cloud and not deleting despite it not running. **What problems is Azure Cosmos DB solving and how is that benefiting you?** I have used Cosmos DB for a project I did during my internship where we needed to host a NoSQL db on cloud to be accessed by using an application to fetch and manipulate data as the functions/tasks were completed ### 44. Excelent for JSON based data **Rating:** 4.0/5.0 stars **Reviewed by:** Nuno C. | Senior Software Developer - ALS Life Sciences Division | Environmental, Information Technology and Services, Enterprise (> 1000 emp.) **Reviewed Date:** April 26, 2018 **What do you like best about Azure Cosmos DB?** I liked the performance and simplicity on using it. When dealing with Json data, I often find it easier to just store it "as is", and by JSON data I can also be meaing POCOs... The broad of APIs available make it very easy to work with for pretty much everybody. **What do you dislike about Azure Cosmos DB?** I really can't say that I dislike anything... I haven't yet had the time to experience it to find any serious flaws. **What problems is Azure Cosmos DB solving and how is that benefiting you?** It provides a simple and easy way, to work with json based documents (or any kind of structure/dialect compatible) without needing to run your own server or having to rely on on-premises infrastructure. ### 45.
