Categories

Tags cio infosec miscellaneous management

Digital services made for consumers are opening up new opportunities and vulnerabilities. With more employees bringing unmanaged devices to the office, business networks can be accessed by many more people. Plus, remote work means that an organization’s IT perimeter is no longer restricted within its walls. By Mihaela Marian.

In the article you will find information on:

  • What is Continuous Adaptive Risk and Trust Assessment (CARTA)?
  • Why is Role-Based Access Control (RBAC) inadequate?
  • How CARTA works
  • How CARTA relates to other risk assessments
  • How to implement Continuous Adaptive Risk and Trust Assessment
  • CARTA vs. Zero-Trust

CARTA continuously evaluates all users and devices and makes contextual access decisions. It has its roots in the Zero-Trust framework, which advocates the idea that no user or device can be trusted, even if they’re already on your network. Companies with zero trust security go to great lengths to ensure that only appropriate access is granted to critical assets.

The hidden costs of serverless observability

Categories

Tags serverless app-development web-development devops microservices

The growing popularity of serverless architectures has led to an increased need for solutions to the modern challenges of microservice observability—one of the most critical components for running high-performing, secure, and resilient serverless applications By @DeveloperSteve.

In this article, we will:

  • Explore the challenges that serverless architectures present to observability
  • Suggest possible solutions
  • Identify the hidden costs of these solutions
  • Discuss ways to mitigate such expenses

In serverless environments, not only are you abstracted from the underlying infrastructure that runs your code, but the distributed, event-driven nature of serverless applications makes traditional approaches to monitoring and debugging ineffective. Serverless functions are often chained through asynchronous event sources such as AWS SNS, SQS, Kinesis, or DynamoDB, making tracing extremely difficult. Interesting read!

Tags performance app-development web-development devops

Observability-driven DevOps and SRE automation can help enterprises achieve SLO goals and reduce MTTR. But, how do you get started? By Rob Jahn.

We refer to this culture and practice as observability-driven DevOps and SRE automation. The article discusses:

  • The role of observability within DevOps
  • The results of observability-driven DevOps speak for themselves
  • 5 steps to achieve observability-driven automation
  • Gain visibility into your existing releases
  • Report and act upon SLOs for your critical services
  • Automate release validation through SLO health scoring
  • Speed up existing delivery pipelines through SLO-driven orchestration
  • Reduce MTTR through SLO-driven remediation

Automating and orchestrating DevOps remediation action and incident response starts by adopting and integrating SLOs within enterprise processes. This automation also relies on integrating tools for releases, notifications, and incident management. This connection empowers platform and site reliability engineers to automate release validation, improve resiliency engineering, support multi-stage delivery, and incorporate automated problem remediation.

Seven website performance metrics to track for better UX

Categories

Tags performance miscellaneous analytics web-development

People expect exceptional performance when they access your site. They want quick load times, stable layouts and quick interactivity, regardless of whether they’re on desktop or mobile. By Ben Schwarz.

However, there are a near-limitless number of ways you could try to measure web performance, and some are far better than others. These 7 website performance metrics allow you to understand how your web page performs across several different page load aspects:

  • Largest Contentful Paint (LCP)
  • Cumulative Layout Shift (CLS)
  • Total Blocking Time (TBT)
  • Interaction to Next Paint (INP)
  • Time to First Byte (TTFB)
  • Number of Third Party Scripts
  • Time to Interactive (TTI)
  • Commonly tracked metrics you should avoid

Too much data can be just as harmful as not enough. For that reason, you need to ensure you’re only tracking the best possible website performance metrics. These three metrics are often tracked but should be avoided: First Input Delay, First Meaningful Paint, Performance Score. Interesting read!

Can you double CPU performance by cooling it with a chip instead of a fan?

Categories

Tags cloud miscellaneous cio fintech servers

A four-year-old company is coming to market soon with an unexpected technology to cool CPUs and SoCs. Frore Systems has developed a cooling chip it calls AirJet that sits on top of a heat-generating chip and cools it without the need for mechanical fans. By Josh Norem.

It’s 2.8mm thick and uses pulsating inlets to suck air into it and exhaust it out the sides. The company claims its “solid-state” cooling solution allows for double the CPU performance compared with using traditional methods. It’s secured $100 million in funding and is now partnering with Intel to bring its technology to the company’s Evo line of laptops.

The AirJet is designed to deal with the ever-shrinking nature of our electronic devices. As phones, tablets, and laptops get smaller, cooling them becomes more difficult. When insufficient cooling is applied, a CPU will throttle, lowering its clock speeds to reduce temps. This naturally results in decreased performance. Frore Systems claims its AirJet tackles this problem better than a fan, without taking much room inside the device. The heart of the issue is how long a CPU can maintain its maximum clock speed with peak power consumption.

According to CEO Dr. Seshu Madhavapeddy in an interview with PCWorld, a 1.8GHz ARM processor with four AirJet Minis will be able to run at 3.5GHz “forever.” An AirJet Pro that’s made for x86 could run at PL1 at 2.1GHz instead of 1.4GHz with a fan. Additionally, the AirJet in a 15-inch laptop would produce just 29 dBA of sound, instead of 42 dBA with a fan. Interesting read!

Blockchain is changing the way the world stores and moves its information. Building on our commitment to help Web3 developers build and deploy new products on blockchain-based platforms, today we’re thrilled to announce Google Cloud’s Blockchain Node Engine. By Amit Zavery, James Tromans.

While self-managed nodes are often difficult to deploy and require constant management, Blockchain Node Engine is a fully managed node-hosting service that can minimize the need for node operations. Web3 companies who require dedicated nodes can relay transactions, deploy smart contracts, and read or write blockchain data with the reliability, performance, and security they expect from Google Cloud compute and network infrastructure.

With Blockchain Node Engine, Web3 organizations enjoy the following benefits:

  • Streamlined provisioning
  • Secure development
  • Fully managed operations

Google Cloud actively monitors the nodes and restarts them during outages as needed. By reducing the need for a dedicated DevOps team, and by offering Google Cloud’s service level agreement (SLA), Blockchain Node Engine can let your team focus on your users instead of your infrastructure.

Building, testing, and monitoring applications in the cloud is a unique challenge. While many organizations have embraced a DevOps methodology, their DevOps machine is still not at the level of maturity they might like it to be. According to a recent survey, 53% work on a team with a ’low level’ of DevOps based on maturity factors. By Dave Armlin.

A big part of achieving cloud DevOps maturity is selecting the right tools for the job. The following tools help automate various parts of the CI/CD pipeline, and make it much easier for DevOps teams to consistently monitor their AWS cloud infrastructure and applications. As with a lot of AWS services, there are several native DevOps tools for AWS users. These services make it easier to provision and manage AWS infrastructure, deploy application code, automate software releases, and monitor the performance of applications and infrastructure.

The article then pays attention to these tools:

  • Native AWS cloud DevOps tools
    • AWS CodePipeline
    • AWS CodeBuild
    • AWS CodeDeploy
    • AWS CodeStar
  • DevOps tools for AWS and multi-cloud environments
    • CircleCI
    • Snyk
    • HashiCorp Terraform
    • Jira Software
