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

New month, new crypto market moves?

To get a roundup of TechCrunch’s biggest and most important crypto stories delivered to your inbox every Thursday at 12 p.m. PT, subscribe here . Welcome back to Chain Reaction. Seems like just yesterday we were ringing in the New Year, but we’ve coasted into February and all seems to be somewhat relaxed (for once) in the crypto world. Last month was filled with crypto companies laying off staff , developments around the existing and new Chapter 11 bankruptcies in the space, partnerships and conversations about potential recovery in 2023. Even with a range of bad news flooding the industry, some cryptocurrencies had a bull run in January, amid the market turmoil. Bitcoin rallied 40% on the month, while ether rose about 32% during the same period. Solana also saw serious recovery, from about $10 in the beginning of the year, near its lowest level since February 2021, up 146% to about $24.3 by the end of January, CoinMarketCap data showed. These market movements could pot

Metaverse app BUD raises another $37M, plans to launch NFTs

BUD , a nascent app taking a shot at creating a metaverse for Gen Z to play and interact with each other, has raised another round of funding in three months. The Singapore-based startup told TechCrunch that it has closed $36.8 million in a Series B round led by Sequoia Capital India, not long after it secured a Series A extension in February . The new infusion brings BUD’s total financing to over $60 million. As with BUD’s previous rounds, this round of raise attracted a handful of prominent China-focused investors — ClearVue Partners, NetEase and Northern Light Venture Capital. Its existing investors GGV Capital, Qiming Venture Partners and Source Code Capital also participated in the round. Founded by two former Snap engineers Risa Feng and Shawn Lin in 2019, BUD lets users create bulbous 3D characters, cutesy virtual assets and richly colored experiences through drag-and-drop and without any coding background. The company declined to reveal its active user size but said its use

Can Arbitrum’s recently formed DAO recover from its messy week?

The TechCrunch Podcast Network has been nominated for two Webbys in the Best Technology Podcast category. You can help TechCrunch win by voting for Chain Reaction , which digs into the wild world of crypto, or Found , which brings you the stories behind the startups by sitting down with the founders themselves. Please take a few moments to vote here . Voting closes April 20. (NB I host Chain Reaction, so vote for my show!) Welcome back to Chain Reaction. This week was pretty bearable as a crypto reporter covering this space. There was less crazy news transpiring, compared to previous weeks (where we saw a number of U.S. government crackdowns on major crypto companies like Binance and Coinbase ). Still, it’s never a dull week in the crypto world. In late March, Arbitrum, an Ethereum scaling solution, transitioned into a decentralized autonomous organization (DAO), after airdropping community members its new token, ARB. DAOs are meant to operate with no central authority and token h
