Conclusion

The Actor Model has been around for quite a while (invented by Carl Hewitt et al in 1973) but in these past few years we have seen an increasing interest in Actors within the industry (Akka, Orleans, Erlang) due to their inherent ability to simplify concurrent problems and their ability to take advantage of distributed resources (a later post will follow later on). The full code listing can be found on Github. Stay safe! Keep hacking! In January Veeam acquired N2WS Software, which provide cloud backup and disaster recovery solutions. One of the products N2WS has is Cloud Protection Manager. This product allows anyone using AWS to easily schedule automated backups and disaster recovery snapshots and have them distributed across availability zones and regions.

Cloud Protection Manager supports the following targets:

EC2 Instances

Volumes

RDS Databases

Aurora Clusters

Redshift Clusters

DynamoDB Tables

Cloud Protection Manager is deployed easily through an AMI in the AWS Marketplace. You can read the installation instructions here

So what does Cloud Protection Manager do that you can’t already do in AWS?

Cloud Protection Manager provides the ability to have a Simple UI to manage all snapshots and recovery. Using Cloud Protection Manager you can easily configure policies
a surrogate Main actor which will wait for the CrawlServer reply - CrawlResponse(root, connection).
