Deck.blue brings a TweetDeck experience to Bluesky users

With over 3 million users and plans to open up more broadly in the months ahead, Bluesky is still establishing itself as an alternative to Twitter/X. However, that hasn’t stopped the developer community from embracing the project and building tools to meet the needs of those fleeing the now Elon Musk-owned social network, formerly known […] © 2024 TechCrunch.

5 tips for dealing with Day 2 Kubernetes operational challenges

Lukas Gentele Contributor

Lukas Gentele is the CEO of Loft Labs, which builds open source developer tooling for Kubernetes.

Kubernetes is a wonderful but complex software that can present significant “Day Two” challenges when put into production.

Developers who are new to Kubernetes — and most are — face a large knowledge gap when they look to sustain and optimize Kubernetes clusters.

In this piece, I will share several ways to address problems as they arise.

Optimize your Kubernetes cluster for cost

As adoption of Kubernetes rises, the need for applications and engineers to access clusters is also growing. However, it is neither feasible nor cost-efficient to always use entire physical clusters to achieve this goal.

Virtual clusters are a great way to reduce costs. In a scenario of 100 developers, we calculated up to 78% savings by using open source virtual clusters.

Leveraging virtual clusters with open source software such as VirtualCluster or vcluster lets Kubernetes operators can run multiple virtual clusters within a single physical cluster, thereby increasing the tenancy of each. By utilizing computing resources via this more communal method, organizations can save on computing costs as opposed to operating entirely separate Kubernetes clusters.

Increase tenant isolation

By leveraging policy engines, it’s possible to implement software security guardrails on your cloud-native Kubernetes infrastructure.

Another great benefit of virtual clusters is that they are isolated from other users on the cluster. This gives each user their own workspace that looks and feels exactly like a physical Kubernetes cluster.

In addition, virtual clusters enable a stricter form of multitenancy compared to namespace-based multitenancy. One of the main concerns with namespace-based multitenancy is that it cannot contain cluster-scoped resources. Many applications must create, or at least access, cluster-scoped resources like nodes, cluster roles, persistent volumes and storage classes.

Virtual clusters also provide security benefits by increasing the isolation in multitenancy clusters via:

  • Full control-plane isolation.
  • Domain Name System (DNS) isolation.
  • Resources created on a single namespace.

Organizations seeking a solution for multitenant applications that provide greater isolation for resources shared among their clusters should consider virtual clusters as an option. On top of saving costs and being simpler to deploy, they are also easier to manage than physical clusters.

Provide integrated development environments

Nimbus launches tiny EV prototype that’s like a motorbike with a roof

As shared e-scooter companies have infiltrated cities and e-bike sales have soared, micromobility has been offered up as a panacea to save us all from the ill humors and packed streets caused by gas-guzzling cars. However, one of the major roadblocks in front of well-intentioned city dwellers who’d love to trade in their cumbersome and environmentally unfriendly vehicles for an e-bike or scooter remains: What happens when it rains? Nimbus, a California-based electric vehicle startup, wants to solve that problem with a simple solution: Put a roof on it. The company recently came out of stealth with a prototype for its Nimbus One, a tiny, three-wheeled EV that “combines the convenience and cost of a motorbike with the safety and comfort of a car.” The Nimbus One. Image Credits: Nimbus The thin, pod-like vehicle is only about 2.75 feet wide and 7.5 feet long, which Nimbus says makes it three to five times smaller than a compact car — the better to park and navigate busy urban stree...

Coinbase Q2 earnings exceed estimates, signaling potential market recovery

Coinbase reported its second quarter earnings Thursday afternoon after the bell, beating market estimates. During Q2, the second largest crypto exchange by trading volume generated total revenues of $707.9 million, down from $772.5 in the previous quarter and $808.3 million in the year-ago quarter. It also had a $97 million net loss and generated a positive adjusted EBITDA of $194 million during the quarter. It was a mixed bag of estimates from analysts prior to the earnings report. Some expected lower results, while others were optimistic . But now crypto bulls and company shareholders alike can breathe a sigh of relief. “One year ago in Q2 2022, we started reducing our expense base to operate more efficiently. One year later, we’re proud to say that our quarterly recurring operating expenses have dropped nearly 50% Y/Y,” the company said in its Q2 2023 shareholder letter . In after-hours trading, shares of Coinbase rose 7% to about $96.70 after its earnings were posted, but re...

Silicon Valley goes to war

At Andreessen Horowitz’s recent American Dynamism summit, Hadrian founder and CEO Chris Power painted a picture of the country in peril. “I’m here to talk to you about an existential risk to the future of the Republic and how Hadrian is trying to solve it,” he began . His words – a mix of rationalism and Marcus Aurelius – were not out of place at the event, which brought together a blend of investors, founders, policymakers and other Washington officials to discuss issues facing the country. A notable number of talks were related to defense and national security, in line with the American Dynamism team’s investment portfolio, which includes bets on defense tech startups like Hadrian, Anduril and Shield AI. Just a few years ago, many investors thought that cutting a check for a defense-first startup was a proposition that simply didn’t make sense. The tides have clearly shifted: a16z is one of many firms that’s taken a stronger interest in defense and national security. PitchBook data...
