3 Trends to Watch in NetOps
Achieving network visibility anywhere, on-premises, in the data center, in the cloud, or from any network is a critical capability for NetOps success.Day Two Cloud 154: Can eBPF Replace Sidecar Proxies?
Today's Day Two Cloud turns the nerd knob to eleven as we delve into kernels, eBPF, sidecar proxies, and service meshes.

35,000 new trees in Nova Scotia
Cloudflare is proud to announce the first 35,000 trees from our commitment to help clean up bad bots (and the climate) have been planted.
Working with our partners at One Tree Planted (OTP), Cloudflare was able to support the restoration of 20 hectares of land at Victoria Park in Nova Scotia, Canada. The 130-year-old natural woodland park is located in the heart of Truro, NS, and includes over 3,000 acres of hiking and biking trails through natural gorges, rivers, and waterfalls, as well as an old-growth eastern hemlock forest.
The planting projects added red spruce, black spruce, eastern white pine, eastern larch, northern red oak, sugar maple, yellow birch, and jack pine to two areas of the park. The first area was a section of the park that recently lost a number of old conifers due to insect attacks. The second was an area previously used as a municipal dump, which has since been covered by a clay cap and topsoil.
Our tree commitment began far from the Canadian woodlands. In 2019, we launched an ambitious tool called Bot Fight Mode, which for the first time fought back against bots, targeting scrapers and other automated actors.

Twilight Zone: File Transfer Causes Link Drop
Long long time ago, we built a multi-protocol WAN network for a large organization. Everything worked great, until we got the weirdest bug report I’ve seen thus far:
When trying to transfer a particular file with DECnet to the central location, the WAN link drops. That does not happen with any other file, or when transferring the same file with TCP/IP. The only way to recover is to power cycle the modem.
Try to figure out what was going on before reading any further ;)
Visibility and Network Security: Using Dynamic Data to Prevent Cyberthreats
A lack of visibility enables threats to originate inside an organization's network security perimeter enabling broad access across the network.Calico workload-centric web application firewall (WAF): A better way to secure cloud-native applications
Container-based web applications built on microservices architecture, whether public-facing or internal, are critical to businesses. This new class of applications is commonly referred to as cloud-native applications. Read on to find out why traditional WAFs are no longer enough to protect cloud-native applications and how Calico’s new workload-centric WAF solves this problem.
Background
HTTP is the lingua franca for modern, RESTful APIs and microservices communication. Traditionally, organizations have deployed WAF at the perimeter level to protect web applications against external attacks. A WAF provides visibility and enforces security controls on external traffic that passes through it. However, for cloud-native applications, where the concept of a perimeter does not exist, the same visibility and control need to be provided at the workload level inside the cluster.
In a survey conducted by information security research center Ponemon Institute to probe the state of the WAF market, more than 600 respondents noted the following:
- 86% of organizations experienced application-layer attacks that bypassed their WAF in the last 12 months.
- While 66% of respondents consider WAF to be an important security tool, over 40% use their WAFs only to generate alerts (not to block attacks).
