Feed: Planet MySQL; Author: Severalnines; Complex, inflexible architectures, redundancy and out-of-date technology, are common problems for companies facing data to cloud migration.  We look to the “clouds,” hoping that we will find there a magic solution to improve operational speed and performance, better workload and scalability, less prone and less complicated architectures. We hope to make our database administrator's life more comfortable. But is it really always a case?  As more enterprises are moving to the cloud, the hybrid model is actually becoming more popular. The hybrid model is seen as a safe model for many businesses.  In fact, it's ... Read More

Feed: Planet big data. Author: Praveen Sripati. Disclosure : The intention is NOT to help others hack, but to make sure they can secure their applications built on top of AWS or some other Cloud. A few mitigations to fix the SSRF vulnerability have been mentioned towards the end of the blog. Introduction  Capital One hosted their Services on AWS and it was hacked (, ). It's a feature in AWS which was exploited and a misconfiguration done by the Capital One which caused the hack by an ex-AWS employee. The information about the hack was every where in the ...

Feed: Recent Announcements. Prior to today, it was challenging to debug or root cause an unresponsive instance. Now, with a simple API call, you have an out-of-band method to trigger a kernel panic (blue screen error in case of Windows operating system) for an EC2 instance. You can use this capability to direct the operating system to perform tasks like creating a crash dump, loading a secondary kernel, or obtaining a call trace. For example, you can configure your instance to generate a crash dump file when a kernel panic is triggered. Crash dumps contain snapshots of your instance's memory, ... Read More

Feed: Recent Announcements. AWS Batch enables developers, scientists, and engineers to easily and efficiently run hundreds of thousands of batch computing jobs on AWS. AWS Batch dynamically provisions the optimal quantity and type of compute resources (e.g., CPU, GPU, or memory-optimized instances) based on the volume and specific resource requirements of the batch jobs submitted. With AWS Batch, there is no need to install and manage batch computing software or server clusters that run your jobs, allowing you to focus on analyzing results and solving problems. AWS Batch plans, schedules, and executes your batch computing workloads across AWS compute services ... Read More

Feed: Recent Announcements. One of the best practices for using EC2 Spot Instances effectively is to be flexible across a wide range of instance types. When customers configure their Auto Scaling group, EC2 Fleet, or Spot Fleet to use multiple instance types with Spot, they must choose a Spot allocation strategy. Spot allocation strategies determine how the Spot Instances in your fleet are fulfilled from Spot Instance pools. The capacity-optimized strategy automatically launches Spot Instances into the most available pools by looking at real-time capacity data and predicting which are the most available. This works well for workloads such as big ... Read More

Feed: AWS Compute Blog. Author: Chad Schmutzer. AWS announces the new capacity-optimized allocation strategy for Amazon EC2 Auto Scaling and EC2 Fleet. This new strategy automatically makes the most efficient use of spare capacity while still taking advantage of the steep discounts offered by Spot Instances. It’s a new way for you to gain easy access to extra EC2 compute capacity in the AWS Cloud.This post compares how the capacity-optimized allocation strategy deploys capacity compared to the current lowest-price allocation strategy. Overview Spot Instances are spare EC2 compute capacity in the AWS Cloud available to you at savings of up ... Read More

Feed: Recent Announcements. Bare metal instances allow EC2 customers to run applications that benefit from deep performance analysis tools, specialized workloads that require direct access to bare metal infrastructure, legacy workloads not supported in virtual environments, and licensing-restricted applications. Bare metal instances also make it possible for customers to run virtualization secured containers such as Clear Linux Containers. Workloads on bare metal instances continue to take advantage of all the comprehensive services and features of the AWS Cloud, such as Amazon Elastic Block Store (EBS), Elastic Load Balancer (ELB) and Amazon Virtual Private Cloud (VPC). I3en instances offer up to ... Read More

Feed: Planet MySQL; Author: Codership; Through Amazon Web Services (AWS), you can create virtual servers (i.e., instances). You can install database and Galera software on them. In this article, we’ll create three nodes, the minimum recommended for a healthy cluster, and configure them to use Galera Cluster. Incidentally, there is a more detailed version of this article in the Tutorial section of our Library. Assumptions & Preparation We’re assuming you have an AWS account and know the basics of the EC2 (Elastic Compute Cloud) platform. To access the nodes, you’ll need an encryption key. Create a new one specifically for ... Read More

Feed: Recent Announcements. Starting today, you can also provide a maximum total price for your EC2 Fleet, enabling you to control the total price you pay per hour for the fleet of instances. When you provide a maximum price, EC2 Fleet will attempt to fulfill all your desired capacity, but will stop provisioning instances before exceeding your maximum fleet price. In other words, when using maximum total price, EC2 Fleet will stop fulfilling instances when either your target capacity or total price is met. Amazon EC2 Fleet and Target Maximum Price is available in all public Regions. To learn more ... Read More

Feed: Recent Announcements. Amazon EC2 Fleet simplifies the provisioning of Amazon EC2 capacity across different Amazon EC2 instance types, Availability Zones, and On-Demand, Amazon EC2 Reserved Instances (RI) and Amazon EC2 Spot purchase models. With a single API call, you can provision capacity across EC2 instance types and purchase models to achieve desired scale, performance, and cost ... Read More
