Amazon Relational Database Serviceの評判・口コミ 全24件

What do you dislike?

There is very little I do not like, but I have had some small issues with compatibility with monitoring tools. These were relatively easy to resolve but could be an issue for those without experienced team supporting them (I am very lucky in having that).

Cost calculations are difficult in anything AWS related. You are charged in lots of small ways. Tiny amounts but they add up quickly.

Very little is available to help you to optimise, so you need to remember you are paying for the hardware, and what you do with it is up to you.

Migration is relatively slow. That is actually the one item I have not been overly happy with. Only had to migrate a production DB once so far, and was quite surprised at AWS not having a faster solution that what we came up with ourselves. It is a common enough issue which they could surely address. That being said - as AWS seem to release a new product/service every day they may already have that solved.

Amazon RDS is very flexible - you can change the capacity without a reboot or downtime. Excellent monitoring tools available, integrations are generally well handled (datadog, logentries, newrelic, etc.). Resilience is great, and even without monitoring tools the AWS console monitoring often provides enough information to diagnose issues or potential issues. Cost is good, for what you get. Ease of install is also good, and the range of engines is wide enough to fit almost anyone's needs.

In terms of security and recovery I have found it is very powerful but you do need to know what you are doing to configure everything correctly, and I would recommend anyone who uses AWS RDS instances to be sure they have a failure plan and run it in test to be sure there isn't any issues with the plan when run in production.

Don't do it without a systems expert and a good DBA. AWS offer you the platform, but you still need to 'build' your own systems. They are very bug, but they don't have everything right - you need to know enough to fill the gaps.

Calculations of costs are hard so consider hiring an AWS expert to work that out for you when comparing against your current solution.

What do you dislike?

If you like the databases RDS have to offer, there's not much to dislike - it's the same software with less hassle. Setting up databases, tables and users is no easier than a self hosted solution. As a cloud service you would expect the service to be essentially limitless like most other AWS services, but the fact it's running on an EC2 VM leaks through in the restrictions on database sizes, storage, memory etc.

What do you like best?

Whatever your database of choice, you'll find that RDS will make the hosting and management pain disappear. Out of the box you get a managed platform where all you need to think about is how much storage you'll need and the performance you want. Amazon take care of maintaining the system, keeping it up to date by installing updates, providing multi-AZ redundancy and increased protection against downtime doe to more care being taken when taking down an instance in the cluster.

Recommendations to others considering the product

If you're targeting AWS, and you're planning to use a relational database, RDS is an excellent choice instead of trying to build your own. Amazon seem to offer stronger protections against restarting RDS instances than you would normally get when deploying your own instances running PostgreSQL etc.

What do you dislike?

I don't like in Amazon RDS we don't have access to underlying machine directly but this does not prevent you to perform most of the DB administrative tasks.

What do you like best?

Amazon RDS provide lot of easy options to configure and fine tune your database. It also allows to select many option for DB instance class to choose which help to manage your cost as per your need. Also it provides various database vendor to choose from like MySQL, Oracle, Postgres etc

Recommendations to others considering the product

Yes definitely I would recommend because it is way more better than on premise solution. ease of backup and high availability are the benefits which are very critical for you online business

What do you dislike?

I am not fond of the way RDS forces me to use certain settings with ways to configure them hidden away in an obscure manner. It also defaults to a scalable server without explicitly stating the payment options for different servers and different plans. I like that its scalable but the scalable versions cost a lot more than the servers that you can accurately estimate usage and have a static upper limit on usage.

What do you like best?

I love how you can set up an RDS server in seconds and use the same user groups, security groups and even vpc settings as the app servers. It helps us avoid so much of the inter server communication troubleshooting at the beginning of a project. Helps us get off the ground much quicker.

Recommendations to others considering the product

Be careful about evaluating your needs for scalability and projected usage. If you have larger sets of data or something that needs realtime interaction, this might not be the highest on your list of options.
