I have ECS at Alibaba cloud, I want to add PostgreSQL, but I can't find any Tutorials on the Internet
how to add PostgreSQL to ECS Alibaba Cloud
There are several ways on using PostgreSQL on Alibaba Cloud:
ApsaraDB RDS for PostgreSQL, which is PaaS solution for PostgreSQL on Alibaba Cloud, so you don't have to worry about installing and configuring PostgreSQL from scratch. It comes with a lot of additional features such as, high availability, disaster recovery, backup, etc. You can find their documentation on creating your PostgreSQL instance.
ApsaraDB for PolarDB, also a PaaS, which is Alibaba Cloud's homegrown RDB fully compatible with MySQL and PostgreSQL. It can support higher storage capacity, nodes clustering, and it's designed for high performance. Check out their documentation on how to create a PostgreSQL cluster.
Self-managed PostgreSQL on ECS - of cause you can still run PostgreSQL on your own ECS. There're plenty of resources on how to install and configure your own PostgreSQL. Check out the DigitalOcean's tutorial on installing PostgreSQL on Ubuntu 20.04.
You have two ways to do it.
you would just take the ECS as a Linux server. you build the PostgreSQL by yourself. it may request higher skills.
you would use the PaaS service, polardb(PostgreSQL) ,you do not need build it step by step ,just use it in 2-3 mins.
the polardb links as below:

Is it possible to achieve active/active multi-region (atleast us-east and us-west) on AWS managed postgres (not the aurora flavor)? Custom managed Postgres cluster might also be acceptable solution.
Questions are welcome. I'm not sure what other information I can provide other than the requirement that the ask is to have postgres run in multiregion active-active configration.
I am using prometheus-operator in Kubernetes and am using EBS volumes as backing store through VolumeClaimTemplates. I would like to instead use Amazon RDS PostgreSQL as a backing store so that I wouldn't have to worry about running out of storage and monitoring storage etc.
I came across remote storage adapters for InfluxDB, Graphite and OpenstDB here but they don't have an adapter for PostgreSQL or MySQL.
Does anyone have any experience making prometheus backup samples to PostgreSQL/MySQL in production environments?
I came across prometheus-postgresql-adapter here but am not sure how it will work with Amazon RDS. If you have any pointers to make it work with RDS, that too will be much appreciated.
Short answer: you can't. Amazon RDS doesn't support that yet. The GitHub issue here says it all: https://github.com/timescale/prometheus-postgresql-adapter/issues/10.
Currently, if you want to use the prometheus-postgresql-adapter, you would need to run the TimescaleDB.
can anyone please give me a high level difference between MongoDB Cloud Manager and Mongodb Atlas. My main aim is to monitor mongodb instances in AWS.
Thanks.
Cloud Manager is used when you want to manage your own infrastructure (you spin up the nodes where MongoDB runs) but still have the benefits of automated backups and monitoring.
Atlas goes one step further by automating everything for you including provisioning the infrastructure. It's a true database as a service fully managed by MongoDB. They hide the complexity of managing servers so all you have to worry about it using MongoDB. It's interesting to note they use AWS (with plans to support Azure and Google) to spin up nodes, perform monitoring, and backups.
The Major difference between Atlas and Cloud manager is that :
Cloud manager is used for monitoring your database deployment and providing the automated back ups in the self hosted environment.
While MongoDB Atlas is used when your deployments are hosted on the MongoDB Servers. So each and ever task is managed by the MongoDB staff. This is basically the database as a service. In case you encounter any issue all you need to open a case with the mongodb and they will help in the investigations of the issue occurred.
Here is an up-to-date answer to this question which explains differences between Atlas, Cloud Manager and also the Ops-Manager:
MongoDB Atlas handles all the complexity of deploying, managing, and healing your deployments on the cloud service provider of your choice (AWS, Azure, and GCP). Atlas pricing details are here 4.
Cloud Manager is a platform for managing MongoDB on the infrastructure of your choice. Cloud Manager pricing details are here 7.
Ops Manager automate, monitor, and back up your MongoDB infrastructure.
Here is the original article and additional resources in the MongoDB community forum: https://www.mongodb.com/community/forums/t/cloud-manager-vs-ops-manager-vs-atlas/42624
We have setup a community postgresql service on Cloud Foundry (IBM Blumix). This is a free service and no automated backup and recovery is supported out of the box.
Is there a way to set up a standby server or a regular backup in case there is any data corruption/failure?
IBM compose and ElephantSQL can provide this service at a cost, butwe are not ready for it yet.
PostgreSQL is an experimental service and there is not a dashboard and other advanced features (Daily backup for example) that you can find in other services that you mentioned. If you want to do a backup you could write an ad-hoc script that 'saves'\exports all tables as you want and run it every day.
If you need PostegreSQL you can create a PostegreSQL by compose service $17.50 / mo for the first GB and $12 for Extra GB )
We used Postgresql Studio and deployed it on IBM Bluemix. The database service was connected to the pgstudio interface (This restricts the access to only connected databases). We also had to make minor changes to pgstudio so that we could use pg_dump with the interface.
The result: We could manually dump the data. This solution works well as we could take regular dumps (though manually).
In the free tier you are right in saying that you cant get the backup. Those features are available only in Compose for PostgresSQL service - but that's a paid service.
We're about to dive into Odoo (OpenERP). We're planning on using Amazon EC2 for the actual installation, and put the postgreSQL database server on Amazon RDS. (like this guide http://toolkt.com/site/install-openerp-server-and-postgresql-on-separate-servers/ )
If the RDS is only allowed to talk to the EC2 server, does this mitigate any security issues compared to a regular Odoo installation (where database and front facing webserver are on the same machine)? Is this an advisable setup?
Input data in your post is very vague to give you exact answer, but you may consider the following:
RDS can talk to EC2 or any other clients and application servers. Connection only depends on your configuration. You can configure VPC and configure/restrict access to your database and application servers there.
Depending on the size of your system (in terms of I/O, number of users , etc), of course you may want to configure separate database instance and application servers. At scale this separation is important.
In short, Nither any Disadvantage nor any security issues.
In Detail Odoo with AWS EC2,
We "SnippetBucket.com" Team had implemeneted already RDS and better know odoo security.
RDS is bit very expensive.
RDS make private instead of public in AWS
make complete secured.
As well AWS Security helps to make extra protection with inbound and outbound ports. Totally Safe.
Note: AWS "RDS Aurora-Postgresql" is 4X faster than official postgresql. AWS RDS support specific versions by AWS.
