This gives fascinating insights into the network topography of our visitors, and how much we might be impacted by high latency regions. Round-trip-time (RTT) is basically a measure of latency—how long did it take to get from one endpoint to another and back again? What is RTT? That’s exactly what this article is about.
Having released this functionality in an Preview Release back in September 2019, we’re now happy to announce the General Availability of our Citrix monitoring extension. Synthetic monitoring: Citrix login availability and performance. Dynatrace news. SAP GUI and other thick-client Windows applications are often delivered via Citrix.
Microsoft Hyper-V is a virtualization platform that manages virtual machines (VMs) on Windows-based systems. Firstly, managing virtual networks can be complex as networking in a virtual environment differs significantly from traditional networking. What is Microsoft Hyper-V? What’s next?
At Netflix, we periodically reevaluate our workloads to optimize utilization of available capacity. While we understand it’s virtually impossible to achieve a linear increase in throughput as the number of vCPUs grow, a near-linear increase is attainable. We decided to move one of our Java microservices?—?let’s let’s call it GS2?—?to
Virtual consensus in Delos , Balakrishnan et al. USENIX is a nonprofit organisation committed to making content and research freely available – both conference proceedings and the recorded presentations of their events. We propose the novel abstraction of a virtual shared log (or VirtualLog). Facebook, Inc. ), OSDI’2020.
These organizations rely heavily on performance, availability, and user satisfaction to drive sales and retain customers. AvailabilityAvailability SLO quantifies the expected level of service availability over a specific time period. Availability is typically expressed in 9’s, such as 99.9%. or 99.99% of the time.
The new Amazon capability enables customers to improve the startup latency of their functions from several seconds to as low as sub-second (up to 10 times faster) at P99 (the 99th latency percentile). This can cause latency outliers and may lead to a poor end-user experience for latency-sensitive applications.
Traditional computing models rely on virtual or physical machines, where each instance includes a complete operating system, CPU cycles, and memory. VMware commercialized the idea of virtual machines, and cloud providers embraced the same concept with services like Amazon EC2, Google Compute, and Azure virtual machines.
Now, customers can use streamed responses to build more responsive applications by sending partial responses to clients as the response becomes available. Customers can use AWS Lambda Response Streaming to improve performance for latency-sensitive applications and return larger payload sizes. Return larger payload sizes.
Performance monitoring Dynatrace can collect performance metrics from Nutanix clusters, including latency, IOPS (Input/Output Operations Per Second), and network throughput. This helps IT teams quickly identify and troubleshoot problems, reducing downtime and ensuring the availability of critical applications.
These releases often assumed ideal conditions such as zero latency, infinite bandwidth, and no network loss, as highlighted in Peter Deutsch’s eight fallacies of distributed systems. Impact of fewer resources, for example, CPU and disk, available to different services and applications.
As a discipline, SRE focuses on improving software system reliability across key categories including availability, performance, latency, efficiency, capacity, and incident response. Collaboration between developers, operations, and product owners enables site reliability engineers to define and meet uptime and availability targets.
Each of these models is suitable for production deployments and high traffic applications, and are available for all of our supported databases, including MySQL , PostgreSQL , Redis™ and MongoDB® database ( Greenplum® database coming soon). High Availability. See the availability and the corresponding downtime measured over one year.
This transition to public, private, and hybrid cloud is driving organizations to automate and virtualize IT operations to lower costs and optimize cloud processes and systems. Besides the traditional system hardware, storage, routers, and software, ITOps also includes virtual components of the network and cloud infrastructure.

We ran performance tests for MongoDB on DigitalOcean vs. AWS vs. Azure and found that DigitalOcean performance was in line with, if not better, on both high throughput and low latency in the deployment. DigitalOcean specialized in SSD-based virtual machines called Droplets that are broken down into four simple categories.
The first was voice control, where you can play a title or search using your virtual assistant with a voice command like “Show me Stranger Things on Netflix.” (See In our case, we value low latency — the faster we can read from KeyValue, the faster these messages can get delivered.
DEM provides an outside-in approach to user monitoring that measures user experience (UX) in real time to ensure applications and services are available, functional, and well-performing across all channels of the digital experience, including web, mobile, and IoT. PC, smartphone, server) or virtual (virtual machines, cloud gateways).
Balancing Low Latency, High Availability and Cloud Choice Cloud hosting is no longer just an option — it’s now, in many cases, the default choice. Let’s look at the top cloud computing use cases, the use cases for which cloud probably isn’t the best route available, and the use cases where a hybrid approach may be best.
After being available in an Early Adopter Release, we’re happy to announce that AWS supporting services are now Generally Available (GA). Supporting services include every service that isn’t available with out-of-the-box Dynatrace monitoring. Monitor and understand additional AWS services. You can also create custom charts.
Relationships are a fundamental aspect of both the physical and virtual worlds. Modern applications need to quickly navigate connections in the physical world of people, cities, and public transit stations as well as the virtual world of search terms, social posts, and genetic code, for example. The importance of relationships.
For example, the number of threads of your process is already available in Dynatrace in most cases, so there is no need to spend the extra effort. Virtualization can be a key player in your process’ performance, and Dynatrace has built-in integrations to bring metrics about the Cloud Infrastructure into your Dynatrace environment.

Since there were no existing solutions available, we needed to build them ourselves. To improve availability, we designed systems where components could fail separately and avoid single points of failure. There is a downside to fetching this data on-demand: this adds latency to the first request to a cluster.
It is very gratifying to see all of our learning and experience become available to our customers in the form of an easy-to-use managed service. Amazon DynamoDB offers low, predictable latencies at any scale. It provides multi-data center replication, high availability, and offers rock-solid durability. Consistency. SimpleDBâ??s
Already, IoT is delivering deep and precise insights to improve virtually every aspect of our lives. Sometimes an internet connection is weak or not available at all, as is often the case in remote locations. This is the exciting future for IoT, and it's closer than you think.
Lift & Shift is where you basically just move physical or virtual hosts to the cloud – essentially you just run your host on somebody else’s hardware. All available in Dynatrace in the UI or through the API! While this is a good start it only provides actionable data for the very classical lift & shift migration.
But we couldn’t adopt the old style approach of upgrading systems through a maintenance outage, as many businesses around the world are relying on our platform for 24/7 availability. Developing a NIC that supported single root IO virtualization allowed us to give each VM its own hardware virtualized NIC. No gatekeepers.
March 26, 2008 doesn't have any delicious desserts associated with it, but that's the day when we launched Availability Zones for Amazon EC2. Powering the virtual instances and other resources that make up the AWS Cloud are real physical data centers with AWS servers in them. How Availability Zones have changed over the years.
Various forms can take shape when discussing workloads within the realm of cloud computing environments – examples include order management databases, collaboration tools, videoconferencing systems, virtual desktops, and disaster recovery mechanisms. This applies to both virtual machines and container-based deployments.
However, it is limited by the available free memory amount, and all data is lost when the server stops. In-Memory Storage Engine, as the name suggests, stores data in memory for faster performance and lower latencies. However, due to its reliance on the virtual memory subsystem, it is not suitable for larger datasets.
On April 24, OReilly Media will be hosting Coding with AI: The End of Software Development as We Know It a live virtual tech conference spotlighting how AI is already supercharging developers, boosting productivity, and providing real value to their organizations. Were experiencing high latency in responses.
A Cassandra database cluster had switched to Ubuntu and noticed write latency increased by over 30%. CLI tools The Cassandra systems were EC2 virtual machine (Xen) instances. Note that Ubuntu also has a frame to show entry into vDSO (virtual dynamic shared object).
In the age of big-data-turned-massive-data, maintaining high availability , aka ultra-reliability, aka ‘uptime’, has become “paramount”, to use a ChatGPT word. So when they don’t get one, they ask again — and again… and again… We thus have two compelling reasons for why high availability is so important: 1. What is high availability?
In the back to basics readings this week I am re-reading a paper from 1995 about the work that I did together with Thorsten on solving the problem of end-to-end low-latency communication on high-speed networks. The lack of low-latency made that distributed systems (e.g.
Back on December 5, 2017, Microsoft announced that they were using AMD EPYC 7551 processors in their storage-optimized Lv2-Series virtual machines. These VMs are not available in all regions, so you will want to check the availability in the Azure region that you are interested in using. Figure 2: Microsoft Project Olympus.
Choosing your database architecture may be the most critical decision you’ll make and has a disproportionate impact on the performance, scalability, and availability of your app. Get it right and your application will seamlessly scale from hundreds to tens of millions of users without difficulty, while remaining performant and available.
To serve such applications, Netflix Drive can persist the ephemeral data in storage tiers which are closer to the application that allow lower read latencies and better economies for read request, since cloud storage reads incur an egress cost. The final encoded copy needs to be persisted and the ephemeral data can be deleted.
We were pushing the limits of what was a leading commercial database at the time and were unable to sustain the availability, scalability and performance needs that our growing Amazon business demanded. Durable and Highly-Available – DynamoDB maintains data durability and 99.99
