The truth is: if the data to be stored is in text format, it can be stored directly; if the data to be stored is a variety of objects, serialize the data to a binary stream before saving it, and deserialize the data during reading.

foramazon EC2 due to the network congestion frequently experienced on thatplatform. Node failures canresult from varous causes such as hardware failures, network outages, and soon. node outages are often transient but can last for extended intervals. anode outage rarely signifies a permanent departure from the cluster, andtherefore doesNot automatically result in permanent removal of the node fromthe ring.

information to arrive. You can adjust the sensitivity of failure detection by configuring the Phi_convict_threshold property. The lower the value, a node that is not responding is more likely to be marked as down, and the higher the value, the shorter the failure may be marked as failure. In most cases, the default value is OK. But it needs to be increased to 10 or 12 on Amazon EC2. (Because of the frequent network congestion), increasing the value t

certificates need to be copied in openvpn configuration, which worries me about potential security issues and will occupy too many VPN Server resources in the future, therefore, this idea can only be abandoned.Solution 3 [abandoned] Later, I came up with a way to share the HTTP Proxy server on the company's intranet with AWS virtual machines through reverse connections. The command used is probably like this: ssh -R 8080:squid.corp.redhat.com:3128 -i ~/.pem/ap-northeast-1-cheshi.pem

Convert instance store support for EBS-backed AmisNote: You cannot convert an instance store-backed Windows Ami to an EBS-backed Ami. And, you can only convert the AMI you own.1. Launch an Amazon Linux instance from an EBS-backed AMI.2. Upload the private key of the *. * Certificate used to bundle the AMI supported by the instance store. (This private key will ensure that only you can access your AMI.) ）3. Set the environment variables for your key ID and Secret key:[

. However, all these efforts at the front end cannot completely prevent the occurrence of every downtime interruption. We still need to actively explore and find new ways to deal with disaster recovery and downtime interruptions. Let us stick to the idea that companies will inevitably experience downtime interruptions, rather than simply trying to block them to design our system. In the face of faults and operation failures, we can provide real application elasticity, because fault protection is
