Everyone is talking about AI after Google Cloud NEXT 2026.
But after building and deploying real agents using Google Cloud’s ADK, MCP servers, and Cloud Run… I realized something most people are missing:
This isn’t about AI anymore — it’s about execution.
The Google Cloud NEXT ’26 Writing Challenge encourages us to explore a key announcement or idea and turn it into something meaningful for developers — not just a summary, but a real perspective.
And this year, one theme was impossible to ignore:
The move from experimental AI to production-ready, agentic systems.
Across keynotes and sessions, Google made it clear that the future isn’t just AI models — it’s what they called the “Agentic Enterprise.”
Some of the biggest signals included:
The introduction of Gemini Enterprise Agent Platform for building and governing agents at scale
The Agent Developer Kit (ADK) and Agent Studio for structured agent development.
A new Agentic Data Cloud approach, enabling agents to securely interact with real data systems.
Advancements in infrastructure like next-gen TPUs optimized for agent workloads.
But here’s the thing:
These announcements only make sense when you actually try to build with them.
That’s exactly what I did.
Instead of just analyzing the announcements, I wanted to test this “Agentic Cloud” idea in practice — by building real systems.
But after building and deploying real agents using Google Cloud’s ADK, MCP servers, and Cloud Run… I realized something most people are missing:
This isn’t about AI anymore — it’s about execution
And after building and deploying multiple agents using Google Cloud’s ADK, MCP integrations, and Cloud Run… I can confidently say:
We are entering the era where developers don’t just build apps — we orchestrate autonomous systems.
I Didn’t Just Watch — I Built
Instead of just watching the announcements, I decided to test the direction myself by building real systems:
- An ADK agent deployed on Cloud Run.
- A Real-Time Surplus Engine using Gemini 3 Flash + AlloyDB.
- A Location Intelligence Agent using MCP servers for BigQuery and Google Maps.
- Multi-agent communication using A2A (Agent-to-Agent) patterns.
Build process, deployment logs, architecture, outputs).
This wasn’t just experimentation — it exposed what Google is really pushing forward.
The Real Shift: From APIs to Autonomous Execution Layers.
The biggest idea behind Google Cloud NEXT 2026 isn’t any single tool.
It’s this:
Google is building an execution layer where AI agents become first-class infrastructure.
With ADK + MCP + Gemini models, you’re no longer just calling APIs.
You’re:
- Connecting agents to live data systems (BigQuery, Maps, DBs).
- Allowing them to -reason + act.
- Enabling -cross-agent collaboration (A2A).
In my Location Intelligence Agent, for example:
- One agent queried BigQuery.
- Another handled geospatial reasoning via Maps.
- The system coordinated results to produce actionable insights.
That’s not a chatbot.
That’s a distributed decision system.
What This Changes for Developers
This shift fundamentally changes how we build.
- Backend Logic Is Becoming Agent-Orchestrated
Instead of writing rigid backend flows:
- You define -capabilities
- Agents decide -how to use them.
This reduces boilerplate — but increases responsibility in design.
2. Real-Time Intelligence Becomes Default.
In my Surplus Engine:
- Gemini 3 Flash processed inputs in real time
- AlloyDB handled structured persistence
- The system responded dynamically to changing conditions
.
This is huge for:
- logistics
- fintech
- marketplaces
- smart city systems
Architecture Breakdown
This system is not a single agent — it’s a coordinated network:
Orchestrator Agent (ADK)
Handles task routing and agent coordination using A2A communication.
Data Agent (BigQuery MCP)
Fetches structured datasets in real-time.
Geo Agent (Google Maps MCP)
Performs location-based reasoning and spatial insights.
Processing Agent (Gemini 3 Flash)
Executes fast reasoning and decision-making logic.
AlloyDB
Stores structured outputs and supports real-time system state.
Cloud Run
Ensures the entire agent system is scalable, stateless, and production-ready.
3. Deployment Is No Longer Optional — It’s Core
Deploying the ADK agent to Cloud Run revealed something important:
If your agent can’t run reliably in production, it doesn’t matter how smart it is.
Google’s push here is clear:
- Agents must be : deployable, scalable, observable.
This is where many “AI demos” fail — but Google is trying to close that gap.
But Let’s Be Honest: This Isn’t Production-Perfect Yet
While the vision is powerful, there are real gaps developers need to be aware of.
⚠️ 1. Debugging Is Still Painful
When an agent makes a wrong decision:
- Tracing the reasoning path is not straightforward
- Observability tools are still evolving
This becomes critical in multi-agent (A2A) systems.
⚠️ 2. MCP Integration Requires Careful Design
Yes, MCP servers make data access powerful — but:
- Poorly structured connections can lead to unpredictable outputs
- Security boundaries need to be explicitly enforced
You’re essentially giving agents access to your data layer.
That’s not something to take lightly.
⚠️ 3. Over-Abstraction Risk
There’s a temptation to let agents “handle everything.”
But in real systems:
- You still need guardrails
- You still need deterministic fallbacks.
Otherwise, you trade control for convenience — and that can backfire.
The Real Opportunity for Startups
This is where things get interesting.
If you understand this shift early, you can build:
- AI-powered internal tools that -replace entire workflows.
- Smart platforms that :adapt in real-time
- Systems that :coordinate data, not just display it.
For example:
- A logistics startup could use a Surplus Engine to dynamically reroute resources
- A real estate platform could use Location Intelligence agents for decision scoring
- A SaaS product could replace dashboards with decision-making agents.
This is not incremental improvement.
It’s a new product category.
What Google described in the keynote as the “Agentic Cloud” isn’t theoretical — it’s already taking shape through tools like ADK, MCP integrations, and platforms like Gemini Enterprise Agent Platform.
Where This Is Headed: Gemini Enterprise Agent Platform
While building with ADK and MCP gave me a hands-on view of agent orchestration, exploring Gemini Enterprise Agent Platform made something even clearer:
Google isn’t just giving developers tools to build agents — it’s building a full ecosystem to manage them at scale.
This platform signals a shift from:
Individual agents → enterprise-grade agent systems.
Experimentation → governed, production-ready intelligence.
What stands out is the focus on:
Agent lifecycle management (creation → deployment → monitoring)
Security and access control across connected systems
Scalability of multi-agent workflows.
At small scale, agents feel like scripts. At enterprise scale, they behave like living systems that require continuous oversight.
This is where most current AI projects fail — not in building agents, but in managing them after deployment.
In other words, the exact challenges I started noticing while building manually with ADK…
Google is already trying to solve at the platform level.
Enterprise Readiness vs Developer Flexibility.
While Gemini Enterprise Agent Platform introduces structure and governance, it also raises a question:
How much control are developers willing to give up for managed intelligence?
There’s a risk that:
abstraction increases
flexibility decreases
experimentation becomes constrained by platform rules
For startups and indie developers, this balance will matter a lot.
If ADK is how developers build agents, then Gemini Enterprise Agent Platform is how organizations will control them.
The Vision Is Clear — The Ecosystem Is Still Maturing
While Google’s “Agentic Enterprise” vision is compelling, there’s still a gap between:
what’s announced
and what’s frictionless for developers today
Tooling like ADK and MCP is powerful, but:
documentation is still evolving
debugging multi-agent systems is complex
and real-world patterns are still being discovered
This isn’t a limitation — it’s a signal:
We’re early.
Final Thought: Cloud Is Becoming Decision Infrastructure
For years, cloud platforms were about compute, storage, and APIs.
But after building with Google Cloud’s agent stack, one thing is clear:
Cloud is no longer just infrastructure — it’s becoming decision infrastructure.
The real shift isn’t that AI can generate responses.
It’s that it can now execute, coordinate, and adapt across real systems.
And that puts us — developers — in a new role.
Not just writing logic…
But designing how systems think, act, and collaborate under pressure.
The tools are still evolving. The gaps are real.
But the direction is undeniable.
The next generation of software won’t be defined by interfaces.
And platforms like Gemini Enterprise Agent Platform hint that this future will be managed, not just built.
It will be defined by intelligent systems that act. I didn’t write this just to share what I built — I wrote it to explore what this shift actually means for us as developers navigating AI-powered systems.
If you’re also experimenting with:
ADK agents
MCP integrations
Cloud Run deployments
or multi-agent systems
I’d really like to hear your experience.
We’re all figuring this out in real time — so if you’re building in this space, your perspective matters too.
What are you building? What challenges are you facing? Or what part of this new direction excites (or concerns) you the most?
