Kongは、唯一のオープンソースAPIマネジメントソフトウェアとして知られ、日本でもヤフーや他の大手テクノロジー企業を顧客に持つ。エンタープライズ版の顧客は、グローバルで100組織を超えたという。同社は2018年9月にサンフランシスコで開催した初のユーザーカンファレンス「Kong Summit 2018」で、Kong 1.0を発表するとともに、「APIマネジメントは死んだ、Kongは『サービスコントロールプラットフォーム』だ」と宣言した。これはもちろん、マイクロサービスにおけるサービスメッシュのニーズが高まってきたことと大いに関係がある。

サービスメッシュというカテゴリで先行するIstioとの関係について。

「今回のサービスメッシュ対応は、最初の一歩だ。Istioはマイクロサービスにおけるエコシステムとして、今後拡大していくと確信している。実際、低レイヤーのネットワークポリシーを構成するのに優れている。そこで、KongではIstioとの統合を進める。私たちは既に、OpenTracingやPrometheusといったCNCF（Cloud Native Computing Foundation）のプロジェクトをサポートしている。サービスメッシュ対応の次に行うのは、Istioとの統合。その次にはgRPCのサポートなどを進めていく。私たちは、Istioを競合相手とは考えていない。マイクロサービス間の通信制御、サーキットブレーカー、ヘルスチェックなどの機能は、もはやコモディティだからだ」」

The global shutdown of 2G and 3G networks is no longer a future plan. It is happening now. Major markets including France, the UK, and Japan have set clear sunset timelines. Operators are moving quickly to free up spectrum and reduce operational costs. But beneath this transition lies a critical problem that many overlook: a pure data network cannot carry traditional voice calls.

The Voice Vacuum of Data-Only Networks

LTE and 5G cores are built on packet-switched architectures. They inherently lack circuit-switched voice capabilities. In the past, operators relied on CSFB (circuit-switched fallback) to hand voice calls down to 2G/3G networks. As 2G/3G disappear, that voice path will be permanently cut. The result is simple: users in perfect 4G or 5G coverage will be unable to make a regular phone call. VoLTE and VoNR are the only solutions, and both require an IMS (IP Multimedia Subsystem) core.

IMS: From Nice-to-Have to Mission-Critical

IMS is a 3GPP-defined control platform for voice and multimedia services. Without IMS, a 4G/5G core is just a high-speed data pipe. It cannot perform call control, signalling interworking, or HD voice. As 2G/3G networks shut down, IMS has shifted from an upgrade option for large carriers to a non-negotiable infrastructure requirement for all operators, especially small and medium operators and MVNOs.

IPLOOK IMS: Legacy Device Support and Smooth Migration to VoLTE/VoNR

IPLOOK offers a full IMS core including P-CSCF, I-CSCF, S-CSCF, application servers, media gateways, and HSS/HLR. During the transition, it interworks with existing 2G/3G networks via media gateways, ensuring that legacy terminals can still make calls and send SMS. At the same time, it natively supports VoLTE and VoNR, enabling a smooth migration of voice services to 4G/5G. This dual-track strategy preserves the existing subscriber base while building a future-ready network.

Tailored for Small and Medium Operators: Lightweight, Cloud-Native, Low-Cost

Traditional IMS solutions can cost millions of dollars with complex hardware and long deployment cycles. IPLOOK targets small and medium operators as well as MVNOs with a lightweight, cloud-native IMS. Based on virtualization and container technology, it runs on public cloud, private cloud, or standard COTS servers with fully decoupled hardware and software, and elastic scaling on demand. Upfront investment is dramatically lower, and time-to-market can be reduced to months or even weeks. For regions with unstable power or limited technical staff, IPLOOK provides core-in-a-box appliances, offline deployment packages, and remote commissioning. A Latin American MVNO went live in just two months; an African national operator successfully deployed stable voice services for millions of users under harsh conditions. IMS also protects post-sunset VoLTE roaming revenue, preventing operators from losing international roaming income.

What is Cloud-Native Application Development?

Cloud-native development is an approach to building applications specifically for cloud environments. These applications are designed to be scalable, flexible, and resilient, using modern architectures and technologies.

Leading platforms like Amazon Web Services, Microsoft Azure, and Google Cloud Platform provide the infrastructure and services required to support cloud-native ecosystems.

Core Principles of Cloud-Native Development

1. Microservices Architecture

Applications are divided into small, independent services that can be developed and deployed separately.

2. Containerization

Tools like Docker allow developers to package applications with all dependencies, ensuring consistency across environments.

3. Container Orchestration

Platforms such as Kubernetes manage container deployment, scaling, and operations automatically.

4. Continuous Integration & Continuous Delivery (CI/CD)

Automated pipelines enable frequent, reliable releases and faster time-to-market.

5. DevOps Culture

Encourages collaboration between development and operations teams for faster and more efficient delivery.

Conclusion

The Executive Crisis For the past five years, corporate boards have praised tech leaders for rapid cloud adoption. But a dangerous financial reckoning is happening right now. The relentless push for "speed to market" drove engineering teams straight into the arms of proprietary, vendor-specific services. We traded our architectural freedom for a temporary burst of velocity.

Now, as enterprise cloud contracts come up for renewal, the C-Suite is discovering a brutal truth: they have zero leverage. When your entire data layer and AI pipeline are deeply hard-coded to a single provider's native ecosystem, the cloud is no longer a competitive utility. It is a monopoly, and your switching costs are astronomical.

The Financial Reality The tech industry mislabeled this as "Vendor Lock-In." It is more accurate to call it a "Digital Hostage Situation." If a cheaper, faster AI model or a more efficient database engine hits the market tomorrow, your enterprise cannot pivot without a multi-million dollar, multi-year rewrite. You are a partner your vendor knows cannot fire them.

The Strategic Pivot "Portability is Leverage" At GYSP, we are advising enterprise leadership to completely abandon the "Cloud Native" dogma and adopt a "Leverage-First" philosophy.

The goal isn't to run on multiple clouds simultaneously—that just doubles your operational overhead. The goal is Portability. The mere ability to move is the only thing that keeps your vendor's pricing honest and your innovation pipeline open.

The Technical Blueprint You cannot negotiate if you cannot migrate. We have published our internal 3-Layer Decoupling Strategy—the exact technical blueprint we use to untangle enterprise architectures, neutralize Data Gravity, and restore vendor leverage.

We have also included our diagnostic Vendor Risk Scorecard so you can measure exactly how deep your "golden handcuffs" go before your next contract renewal.
