Apache ShardingSphere is an open source distributed database toolkit. It enhances any database with data sharding, elastic scaling, encryption, and many other capabilities. Deploying and maintaining ShardingSphere-Proxy clusters and load balancing manually can be labor-intensive and time-consuming. To address this issue, Apache ShardingSphere offers ShardingSphere on Cloud, a collection of cloud-based solutions.
ShardingSphere-on-Cloud includes automated deployment scripts to virtual machines in cloud environments. It also includes tools for a Kubernetes cloud-native environment and a variety of hands-on content for high availability, observability, security policy compliance, and more. This includes Helm Charts, an Operator, and automatic horizontal scaling.

The new cloud project provides the following capabilities:
- Helm Charts-based ShardingSphere-Proxy for one-click deployment in Kubernetes environments.
- Operator-based ShardingSphere-Proxy for one-click deployment and automated maintenance in Kubernetes environments.
- Amazon Web Services (AWS) CloudFormation-based ShardingSphere-Proxy for rapid deployment.
- Terraform-based rapid deployment of ShardingSphere-Proxy in AWS environments.
This article demonstrates one of the fundamental capabilities of ShardingSphere on Cloud: One-click deployment of ShardingSphere-Proxy clusters in Kubernetes using Helm Charts.
-
Use the following three-line command to create a three-node ShardingSphere-Proxy cluster within a Kubernetes cluster with the default configuration and serve it through the Service:
$ helm repo add shardingsphere https://apache.github.io/shardingsphere-on-cloud $ helm repo update $ helm install shardingsphere-proxy shardingsphere/apache-shardingsphere-proxy-charts -n shardingsphere

-
The application can access the ShardingSphere-Proxy cluster through the svc domain:
$ kubectl run mysql-client --image=mysql:5.7.36 \ --image-pull-policy=IfNotPresent -- sleep 300 $ kubectl exec -i -t mysql-client -- mysql \ -h shardingsphere-proxy-apache-shardingsphere-proxy.shardingsphere.svc.cluster.local \ -P3307 -uroot -proot

It's as easy as that. You're running ShardingSphere on the cloud, and that's just the beginning. For more advanced features, refer to the official ShardingSphere-on-Cloud documentation.

Preserving the open web through Drupal

Just because I share content online doesn't mean I want to share control over it.
My website is a perfect example of what I mean. I take photos nearly everywhere I go: To date, I have more than 10,000 photos uploaded to my Drupal site. Using something like Instagram might be easier, but my photos are precious to me, which is why I feel so strongly about preserving the open web.
There are many reasons proprietary platforms don't meet my requirements for sharing. First, I like to own my data. If you think back to early social media sites like MySpace, they infamously lost massive amounts of user data. Artists lost their music. People lost their photos. This sort of thing still happens on Facebook and other social media sites.
[ Related read: How to switch from Twitter to Mastodon ]
Second, I don't like how proprietary platforms limit my creative freedom. Websites built on proprietary platforms often use templates, which makes them all look the same. Similar trends are happening in the design world — minimalist design has led to the death of detail. From doorbells to templated websites, unique design elements have been eliminated in favor of safe neutrals in an attempt to please everyone. This trend strips the personality right out from under websites, which used to be highly personal. Remember when people's early internet homepages actually felt like their digital homes?
Finally, I don't like how proprietary platforms treat my friends and family. People get tracked every time you upload a photo to a social media site. They're more like social monetization sites that make you scroll for hours, only to target you with ads. The problem got so bad that even Apple added tracking protection to WebKit in its Safari browser. Now, many social sites have their own in-app browsers as a workaround, so they can still track you.
I want the open web to win. That's why the ongoing enhancements to Drupal are such good news.
A world where good software winsA few decades ago, the web was about getting information. Today, it's ingrained in every aspect of daily life. People can pay bills, work, socialize, get healthcare—and still get information. As more and more activities take place on the web, there's an even greater responsibility to ensure that the open web is inclusive of every person and accounts for everyone's safety. When people are excluded from accessing online experiences, they're cut out of rewarding careers, independent lifestyles, and the social interactions and friendships that bring people together. That's why good software and open source projects like Drupal are so important to protecting and growing the open web.
Good software is open, flexible, pro-privacy, secure, and doesn't lock you in. Good software lets you control your own code and your own data. It lets you prioritize what's important to you, whether that's accessibility, privacy, or something else. You're fully in control of your own destiny.
Good software also cares about end users. To that end, the Drupal community has been working on making software that solves people's problems and brings even more users into the community. This will be our priority now and in the future. We want to build a world where good software wins.
Opening up Drupal to more users with improved composabilityMany people and organizations around the world want to build ambitious web experiences that are secure, scalable, and mindful of privacy—differentiated experiences that lead with accessibility. Drupal is for them, in part because of its composability.
Composability is one of the hottest trends in the technology market right now. Composability starts with software that's modular and made up of components. With more than 40,000 modules, Drupal meets that requirement. However, there's so much more to composability than an architecture for developers. Composability is a new way of doing business.
It's about providing low-code or no-code tools that enable business users to participate in digital experience building. Even non-technical users can do this from Drupal's user interface. Layout Builder, a visual design tool, helps content editors and site builders easily and quickly create visual layouts for displaying various content types. Composability is also about decoupling the front end from the back end and allowing users to push content and data to different touchpoints on the web. Drupal has been investing in headless and decoupled architectures for almost a decade and now ships with headless capabilities out of the box.
Finally, because composability offers limitless possibilities to combine modules, it can easily get complicated. You need a good way to search for modules and update sites to manage dependencies and versions. Drupal uses a tool called Project Browser to make it easier for site builders to browse innovative modules built by the community. Distributions and recipes allow users to bundle modules and configurations together for reusable, prepackaged business solutions.

If you haven't checked out Drupal in a while, I recommend you see it for yourself. The latest version, Drupal 10, recently shipped with even more innovations including:
- Modernized front-end experience (Olivero theme)
- Modernized back-end experience (Claro theme)
- An improved content editing experience (CKEditor 5)
- Improved developer experience built on Symfony 6.2 with support for PHP 8.2
- A new theme generator
- And more
The launch of Drupal 10 comes at a good time. There's so much turmoil happening within the top social networking sites. If nothing else, it's a good reminder that preserving and promoting an open web is more important than ever before. Open source, the IndieWeb, the Fediverse, decentralized social media platforms, and even RSS are all seeing newfound appreciation and adoption as people realize the drawbacks of communicating and collaborating over proprietary platforms.
An open web means opportunity for all. And open source gives everyone the freedom to understand how their software works, to collectively improve it, and to build the web better for future generations. The main focus of Drupal 10 was to bring even more site builders to Drupal. In that way, Drupal will help extend the open web's reach and protect its long-term well-being for years to come.
Drupal updates create opportunities for everyone to participate in the open web.

It was just four years ago in Ubuntu 19.10 that Ubuntu's desktop installer added OpenZFS support for carrying out root file-system installations atop this ZFS file-system. Since then the Canonical/Ubuntu interest has waned. Ahead of the Ubuntu 23.04 release this week, I tried out the Ubuntu Lunar Lobster daily snapshot this weekend to find the OpenZFS install support with Ubuntu's new desktop installer to still be missing...
