Key Insights from the 2025 GigaOm Radar for Container Networking

Why Calico was named as a Leader in the GigaOm Radar Report for Container Networking

In 2025, as modern applications became ever more distributed and the use of Kubernetes continued to proliferate, the role of container networking was critical. Today’s enterprises demand networking solutions that can scale, secure, and connect services reliably, whether those services run across multiple clouds, hybrid environments, or on-premises clusters.

We’re proud to share insights from the recently released 2025 GigaOm Radar Report for Container Networking, a comprehensive evaluation of vendor solutions across innovation, platform maturity, and real-world operational capabilities, and to highlight the unique strengths of Calico Cloud and Calico Enterprise as recognized in the report.

What the GigaOm Radar Report on Container Networking Covers

GigaOm’s Radar Report evaluates container networking solutions across a spectrum of criteria that matter most to IT infrastructure teams and cloud architects. These include:

  • Network Policy Definition: Declarative, granular network policies consistently enforced across clusters
  • Routing (Layer 3/Layer 4): Scalable routing between pods, services, and non-container workloads using Layer 3 (IP) and Layer 4 (TCP) protocols
  • Layer 7 Networking: Application-aware traffic handling with visibility using Layer 7 protocols
  • Load Balancing: Controls how traffic is distributed across instances, using latency Continue reading

Negara dengan Kasus Kejahatan Tertinggi di Dunia: Trinidad and Tobago

Ancaman Kriminalitas Tinggi di Trinidad and Tobago

Trinidad and Tobago sering masuk daftar negara dengan kasus kejahatan tertinggi di dunia. Meskipun negara ini indah, tingkat kriminalitasnya terus mengkhawatirkan. Pemerintah bergerak cepat menghadapi masalah ini. Namun, kelompok kriminal semakin nekat. Karena itu, warganya hidup waspada setiap waktu.

Selain itu, kota besar seperti Port of Spain mengalami situasi paling buruk. Pembunuhan, penculikan, serta perampokan sering terjadi. Bahkan, serangan geng mendominasi lingkungan padat penduduk. Obat terlarang juga menjadi penyebab utama meningkatnya konflik antar kelompok. Oleh karena itu, penduduk menginginkan keamanan lebih baik.

Meskipun pariwisata penting, wisatawan tetap berhati-hati. Banyak kasus terjadi dekat lokasi wisata. Sementara itu, polisi terus memperkuat operasi keamanan. Namun, hasilnya belum signifikan. Tindak kejahatan berjalan cepat, karena pelaku semakin berani.

Berikut tabel ringkas situasi kriminal di negara ini:

Jenis Kejahatan Tingkat Kejadian Penyebab Utama
Pembunuhan Sangat tinggi Konflik antar geng
Penculikan Tinggi Pemerasan & kriminal terorganisir
Perampokan Tinggi Kejahatan jalanan
Narkotika Ekstrem Jalur perdagangan internasional

Akar Masalah Kejahatan di Trinidad and Tobago

Masalah kriminalitas ekstrem ini tidak muncul begitu saja. Banyak faktor mempengaruhi peningkatan kekerasan. Pertama, penyelundupan Continue reading

BGP Updates cin 2025

The first part of this annual report on BGP for the year 2024 looked at the size of the routing table and some projections of table growth for both IPv4 and IPv6. However, the scalability of BGP as the Internet’s routing protocol is not just dependant on the number of prefixes carried in the routing table. BGP protocol behaviour in the form of dynamic routing updates are also part of this story. This second part of this report looks at the profile of BGP updates across 2023 to assess whether the stability of the routing system, as measured by the level of BGP update activity, is changing.

I just passed the AWS Advanced Networking Specialty

It’s been almost exactly 11 years since I passed the R&S CCIE lab in Brussels, and now it was time to go with something more cloudy 🙂 I just passed the AWS Advanced Networking Specialty, and unlike CCIE I did this one on my first attempt. I did stay pretty much in networking during the last years, but shifted to significantly less Cisco and quite much into cloud architecture – mostly AWS. Since networking is the heart of every cloud architecture, and after 4 years of hands-on work with complex AWS networking projects, I decided it was time to validate

Human Cognition Can’t Keep Up With Modern Networks. What’s Next?

Sanil Nambiar, client engagement lead, AI for networks, at IBM: Assembling the infrastructure organizations will need for AI. “The strategy, obviously, is hybrid cloud, data and AI and automation working together as an architecture,” Nambiar told me in this episode of The New Stack Makers. IBM has invested in what he calls “three foundational platforms” because each offers capabilities essential to AI infrastructure. Red Hat, a hybrid cloud platform, is needed “for that consistent runtime across on-prem and cloud,” he said. HashiCorp offers “life cycle control and policy-driven automation.” And Confluent is for “real-time, contextual, trustworthy data access for AI.” All of these platforms are needed, Nambiar said, because  “AI does not sit on top of chaos and magically fix it. You really need environments which are consistent, infrastructure that is programmable, data that moves in real time.” The Core Challenges of Modern Network Operations The new complexity AI introduces has added to the challenges networking Continue reading

Sidecarless mTLS in Kubernetes: How Istio Ambient Mesh and ztunnel Enable Zero Trust

Encrypting internal traffic and enforcing mutual (mTLS), a form of TLS in which both the client and server authenticate each other using X.509 certificates., has transitioned from a “nice-to-have” to a hard requirement, especially in Kubernetes environments where everything can talk to everything else by default. Whether your objectives are regulatory compliance, or simply aligning to the principles of Zero Trust, the goal is the same: to ensure every connection is encrypted, authenticated, and authorized.

Delivering Cluster-Wide mTLS Without Sidecars

The word ‘service mesh’ is bandied about as the ideal solution for implementing zero-trust security but it comes at a price often too high for organizations to accept. In addition to a steep learning curve, deploying a service mesh with a sidecar proxy in every pod scales poorly, driving up CPU and memory consumption and creating ongoing maintenance challenges for cluster operators.

Istio Ambient Mode addresses these pain points by decoupling the mesh from the application and splitting the service mesh into two distinct layers: mTLS and L7 traffic management, neither of which needs to run as a sidecar on a pod. By separating these domains, Istio allows platform engineers to implement mTLS cluster-wide without the complexity of Continue reading

UET Congestion Management: CCC Base RTT

Calculating Base RTT

[Edit: January 7 2026, RTT role in CWND adjustment process]

As described in the previous section, the Bandwidth-Delay Product (BDP) is a baseline value used when setting the maximum size (MaxWnd) of the Congestion Window (CWND). The BDP is calculated by multiplying the lowest link speed among the source and destination nodes by the Base Round-Trip Time (Base_RTT).

In addition to its role in BDP calculation, Base_RTT plays a key role in the CWND adjustment process. During operation, the RTT measured for each packet is compared against the Base_RTT. If the measured RTT is significantly higher than the Base_RTT, the CWND is reduced. If the RTT is close to or lower than the Base_RTT, the CWND is allowed to increase.

This adjustment process is described in more detail in the upcoming sections.

The config_base_rtt parameter represents the RTT of the longest path between sender and receiver when no other packets are in flight. In other words, it reflects the minimum RTT under uncongested conditions. Figure 6-7 illustrates the individual delay components that together form the RTT.

Serialization Delay: The network shown in Figure 6-7 supports jumbo frames with an MTU of 9216 bytes. Serialization delay is measured Continue reading
