Introduction It is awesome to have some useful services like ElasticSearch managed by AWS , so you don't have to care about patching, monitoring, etc.  When it comes to backup management for indexes, Amazon ElasticSearch includes automated snapshots. Automated snapshots are only for cluster recovery. You can use them to restore your domain in the event of red cluster status or other data loss. Amazon ES stores automated snapshots in a preconfigured Amazon S3 bucket at no additional charge. In particular, if you are using a higher version than 5.3, Amazon ElasticSearch takes hourly automated snapshots and retains up to 336 of them for 14 days. However, this policy might not be enough if you need to keep your snapshots for a longer 15 days, or you need to take a snapshot to create a new cluster in another region, subnet, etc. If you have different requirements to manage your snapshots, you will have to work with manual snapshots. For this part, AWS does not offer a good managed exper

In "Working Effectively with Legacy Code" Michael Feathers introduced a definition of legacy code as code without tests, since a code without tests is difficult to maintain, extend and evolve. It doesn't matter if you are using the latest technologies, if you don't test your code, it will hard to change without breaking anything, which will make it rigid and difficult to maintain. Remember that unit tests are the base in the testing pyramid. In order to ensure that you are covering with unit tests the most important part of our application, code coverage can be helpful to detect where you have lack of tests. Code coverage is a tool offered by products like ReSharper or the Enterprise version of Visual Studio . However, these products are not free and you might not want to pay for this essential feature. But if you are working with dotnet core, it is quite easy to get a code coverage report thanks to ReportGenerator package. In order to generate your tests, first
