What would be the best option for a MongoDB instance on AWS? To address this question, we explore MongoDB performance on various AWS EC2 memory-optimized instances as they are recommended for database usage. Benchmarks were conducted on seven different R-Based instance...
The original general-purpose “one size fits all” instance has evolved into six families, each one optimized for specific uses cases, with over 600 generally available instances in all. New M7g and R7g Today I am happy to tell you about the newest Amazon EC2 instance...
With this launch, AWS Compute Optimizer now supports a total of 425 EC2 instance types. Previously, AWS Compute Optimizer only analyzed “Memory % Committed Bytes in Use” as memory metric for EC2 Windows instances. AWS Compute Optimizer now uses “Available Mbytes”, ...
Supported instance types on AWS You need to determine the instance type you would like to upgrade to based on the CPU and memory specifications. GitHub recommends a memory-optimized instance for GitHub Enterprise Server. For more information, see Ama...
改变单个 EC2 instance 的规格(垂直扩容)! 方法也是滚动替换,最后替换主库,主库会主动下线,通过 log 传递给从库,快速进行选主(或者切主),可以减小 downtime 时间 修改分片数 增加分片用来扩展读写性能,增加内存的容量(扩大数据库规模)。 数据迁移和 拓扑变更两个阶段,数据迁移和 redis一样,源端获取迁移 slot ...
EC2 High Memory instances are built on AWS Nitro System with up to 24TB of memory in a single instance to deliver scalable and elastic infrastructure capabilities for large in-memory databases, such as SAP HANA.
Provision a single node EKS cluster running an EC2 instance type of m5.large. Apply the following deployment resource. apiVersion: apps/v1 kind: Deployment metadata: annotations: labels: app: stress-ng name: stress-ng spec: selector: matchLabels: app: stress-ng template: metadata: labels:...
Please forgive my N00bish question, I'm new supporting mysql databases. I'm working on a mysql-db (5.0.77) running on an EC2 m1.large instance. (2 virtual cores / 7.5 gigs of ram). Lately the database has been running out of memory and I'm hoping that tuning the my.cnf may re...
The following is example output for an m4.large instance that's running the Amazon ECS-optimized Amazon Linux AMI. total used free shared buffers cached Mem: 8373026816 348180480 8024846336 90112 25534464 205418496 -/+ buffers/cache: 117227520 8255799296 This instance has 8373026816 bytes of total ...
In contrast, for RDDs with narrow dependencies on data in stable storage, such as the points in our logistic regression example (§4.1) and the immutable vertex states in our optimized variant of Pregel (§4.3.1), checkpointing may never be worthwhile. Whenever a node fails, lost partitions...
