Starting today, we’re thrilled to announce you can run the same tunnel from multiple instances of cloudflared simultaneously. This enables graceful restarts, elastic auto-scaling, easier Kubernetes integration, and more reliable tunnels.
I work on Cloudflare Tunnel, a product our customers use to connect their services and private networks to Cloudflare without poking holes in their firewall. Tunnel connections are managed by cloudflared
, a tool that runs in your environment and connects your services to the Internet while ensuring that all its traffic goes through Cloudflare.
Say you have some local service (a website, an API, or a TCP server), and you want to securely expose it to the Internet using a Cloudflare Tunnel. First, download cloudflared, which is a “connector” that connects your local service to the Internet through Cloudflare. You can then connect that service to Cloudflare and generate a DNS entry with a single command:
cloudflared tunnel create --name mytunnel --url http://localhost:8080 --hostname example.com
This creates a tunnel called “mytunnel”, and configures your DNS to map example.com to that tunnel. Then cloudflared connects to the Cloudflare network. When the Cloudflare network receives an incoming request for example.com, it looks up Continue reading
Application initiatives are driving better business outcomes, an elevated customer experience, innovative digital services, and the anywhere workforce. Organizations surveyed by VMware report that 90% of app initiatives are focused on modernization(1). Using a container-based microservices architecture and Kubernetes, app modernization enables rapid feature releases, higher resiliency, and on-demand scalability. This approach can break apps into thousands of microservices deployed across a heterogeneous and often distributed environment. VMware research also shows 80% of surveyed customers today deploy applications in a distributed model across data center, cloud, and edge(2).
Enterprises are deploying their applications across multiple clusters in the data center and across multiple public or private clouds (as an extension of on-premises infrastructure) to support disaster avoidance, cost reduction, regulatory compliance, and more.

While app teams can quickly develop and validate Kubernetes applications in dev environments, a very different set of security, connectivity, and operational considerations awaits networking and operations teams deploying applications to production environments. These teams face new challenges as they transition to production with existing applications — even more so when applications are distributed across multiple infrastructures, clusters, and clouds.

In the previous blog post in this series, we figured out that you might not need link-layer addresses on point-to-point links. We also started exploring whether you need network-layer addresses on individual interfaces but didn’t get very far. We’ll fix that today and discover the secrets behind IP address-per-interface design.
In the early days of computer networking, there were three common addressing paradigms:

We’re excited to announce Calico v3.19.0! This release includes a number of cool new features as well as bug fixes. Thank you to each one of the contributors to this release! For detailed release notes, please go here. Here are some highlights from the release…
We’re very excited to announce that Calico v3.19 includes tech-preview support for FD.io’s Vector Packet Processing (VPP) data plane, joining Calico’s existing iptables, eBPF, and Windows dataplanes.
The VPP data plane promises high performance Kubernetes networking with support for network policy, encryption via WireGuard or IPSec, and MagLev service load balancing.
Interested? Try it out by following the tech-preview getting started guide!
In previous versions of Calico, the “calicoctl” command line tool was required to properly manage Calico API resources. In Calico v3.19, we’ve introduced a new tech-preview feature that allows you to manage all projectcalico.org API resources directly with kubectl using an optional API server add-on.
Try it out on your cluster by following the guide!
Calico v3.19 introduces support for Calico for Windows users to deploy containers using containerd Continue reading
I took the exam on 8th May 2021 and was able to crack it .Now you can call me AWS certified Associate .
I started thinking of giving the AWS associate exam more than a year back when my company provided us the free license of cloud Guru. We started a group of individuals who were interested in learning and taking the AWS associate exam. Our plan was to go through the cloud guru videos twice in a week during office hrs ( Allocated 1 hrs for learning ) and discuss any doubts related to topics. It all went very well for few weeks and suddenly people started missing sessions due to different reasons such as office meeting and workload. The group which started with 30 people reduced to 10 now and unfortunately I too dropped due to timing clash and office workload.
Almost after 6 months, again I started going through cloud Guru Videos and this time I was able to complete it and at that time i can easily rate myself 6 out of 10.
I went through AWS FAQ’s , I must say that they are must if you are preparing to take AWS exam.
I didn’t stop, Continue reading
The Cloudflare Web Application Firewall (WAF) protects websites and applications from malicious traffic attempting to exploit vulnerabilities in server software. It’s a critical piece of the broader security posture of your application. With that in mind, we made sure improvements to the Web Application Firewall dashboard experience made it easier to enable the WAF and configure rules to match the specific requirements of an application. In this post, I’ll share parts of the process we followed and the rationale behind the decisions we took when designing the new Web Application Firewall dashboard experience.
I’ve separated out my design process into three stages:
We support a range of customers — individual developers or hobbyists, small/medium-sized businesses where it’s common for a developer to fulfil multiple roles and responsibilities, through to large global enterprises where often there is an entire department dedicated to information security. Traditionally, product development teams use techniques such Continue reading
If there were doubts about how important the Internet is for everyone, 2020 put those to rest. As we push forward through this turbulent time, I want to take a moment to share some inspiration.
