Can I use MongoDB with Amazon EC2 small instance? - Server
Your AWS DMS instance can be unavailable for several reasons, such as a previously requested modification or a maintenance-window action. The time required to reboot an AWS DMS replication instance is typically small (under 5 minutes). In the next screen pick the desired Instance Type (e.g t2.large) then select Apply; To restart the stopped instance, select the instance, choose Actions, select Instance State, and then choose Start; Changing a running AWS EC2 instance type from a C or an M class to a T class takes just minutes! In general, more expensive instances are faster. For example, our Python (Django) web application runs about twice as fast on a c1.xlarge as on a c1.medium, even with only a single thread running--and the max memory requirements for a single thre AWS Pricing Calculator lets you explore AWS services, and create an estimate for the cost of your use cases on AWS. Processing power: Every instance has a certain number of EC2 compute units (ECU), which is a benchmarked amount of processing power (the equivalent of the CPU capacity of a 1.0-1.2 GHz 2007 Opteron or 2007 Xeon processor). For example, the small instance in AWS has 1 EC2 compute unit, or 1 ECU. Amazon EC2 G4 instances deliver a cost-effective GPU instance for deploying machine learning models in production and graphics-intensive applications. G4 instances provide the latest generation NVIDIA T4 GPUs, AWS custom Intel Cascade Lake CPUs, up to 100 Gbps of networking throughput, and up to 1.8 TB of local NVMe storage. AWS makes it easy to launch your first compute instance by offering a wide range of prebuilt and optimized Amazon Machine Images (AMIs) that you can load onto a newly created instance.
For instance, make sure to use a snapshot retention policy. Rightsize: Analyze usage statistics and capacity demands to make sure all your instances are right-sized. AWS offers useful tools for this, such as AWS CloudWatch and AWS CLI. By fine-tuning your resources to meet your actual performance needs, you can considerably lower your storage
AWS DMS uses a replication instance to connect to your source data store, read the source data, and format the data for consumption by the target data store. A replication instance also loads the data into the target data store. Most of this processing happens in memory. However, large transactions might require some buffering on disk. How to safely upgrade an Amazon EC2 instance from t1.micro Using the AWS Management Console Go to "Volumes" and create a Snapshot of your instance's volume. Go to "Snapshots" and select "Create Image from Snapshot". Go to "AMIs" and select "Launch Instance" and choose your "Instance Type" etc. AWS Pricing Calculator
Which is better: 4 small EC2 instances vs. 1 large EC2
