The AWS team confirmed a known hardware issue affecting a certain amount of EC2 machines in that region. The fast action by our ACE Team that followed up with AWS and the fast replacement of hardware by AWS brought the system back to its original state shortly after the investigation began.
Two of the main reasons we hear are often due to migration of hardware, or the need to split data between servers. Migrating ScaleGrid for Redis™ data from one server to another is a common requirement that we hear from our customers. Typically, you want to migrate with minimal downtime while using the standard Redis […].
However, making the IoT product work well requires knowing how to optimize software and hardware-related aspects. Ensure the IoT Device Has Adequate Hardware People must first consider how they will use the IoT device and then evaluate whether it has the appropriate hardware capabilities to meet relevant current and future needs.
But what is the metric that shows service hardware monopolization by a group of users? Quality metrics contain: The ratio of successfully processed requests. Distribution of processing time between requests. Number of requests dependent curves. This metric absence reduces the quality and user satisfaction of the service.
This centralization means all aspects of the system can share underlying hardware, are generally written in the same programming language, and the operating system level monitoring and diagnostic tools can help developers understand the entire state of the system.
In FaaS environments, providers manage all the hardware. Alternatively, in a CaaS model, businesses can directly access and manage containers on hardware. Meanwhile, CaaS adds an abstraction layer that enables companies to run containers on VMs or directly on bare-metal resources. CaaS vs. FaaS.
In modern production environments, there are numerous hardware and software hooks that can be adjusted to improve latency and throughput. To achieve this level of performance, such systems require dedicated CPU cores that are free from interruptions by other processes, together with wider system tuning.
When we wanted to add a location, we had to ship hardware and get someone to install that hardware in a rack with power and network. Hardware was outdated. Fixed hardware is a single point of failure – even when we had redundant machines. Keep hardware and browsers updated at all times. Sound easy?
Hardware infrastructure. This is a guest post by Hugues Alary , Lead Engineer at Betabrand , a retail clothing company and crowdfunding platform, based in San Francisco. This article was originally published here. Early infrastructure. The scalability and maintainability issue. Scaling development processes. The advent of Docker. Kubernetes.
Vulnerabilities or hardware failures can disrupt deployments and compromise application security. For instance, if a Kubernetes cluster experiences a hardware failure during deployment, it can lead to service disruptions and affect the user experience.
The fail-over condition arises due to uncontrolled network failure, OS failure, hardware failure or DR drill. Many organizations spend huge amounts of time manually settling business transactions when there is a complete fail-over of an application or site zone failure to another application site zone.
This allows teams to sidestep much of the cost and time associated with managing hardware, platforms, and operating systems on-premises, while also gaining the flexibility to scale rapidly and efficiently. Performing updates, installing software, and resolving hardware issues requires up to 17 hours of developer time every week.
In nutshell, Compatibility Test is a kind of Software test to confirm whether your software is competent enough of running on various Mobile devices, operating systems, hardware, applications, or network environments
Besides the traditional system hardware, storage, routers, and software, ITOps also includes virtual components of the network and cloud infrastructure. Although modern cloud systems simplify tasks, such as deploying apps and provisioning new hardware and servers, hybrid cloud and multicloud environments are often complex.
Previously, proprietary hardware performed functions like routers, firewalls, load balancers, etc. In IBM Cloud, we have proprietary hardware like the FortiGate firewall that resides inside IBM Cloud data centers today. These hardware functions are packaged as virtual machine images in a VNF.
