CIONET Round Table: Securing Your Digital Crown Jewels

The modern cyber threat landscape has evolved from simple data breaches to sophisticated, systemic attacks designed to cripple an entire organisation. Ransomware, in particular, has made traditional backup and recovery strategies insufficient, as attackers often compromise backups before launching their main assault. In this new reality, the question is no longer "if" an attack will happen, but "when” and how quickly you can recover. Furthermore, regulations like DORA and NIS2 are making robust recovery a legal imperative, compelling businesses to adopt solutions that can guarantee data integrity and business continuity even after a catastrophic cyber event, making a Cybervault a critical component of regulatory compliance.

The New CISO - CIONET Belgium: Community Event

The Role of the Chief Information Security Officer (CISO) The role of the Chief Information Security Officer (CISO) is no longer confined to securing the network perimeter. As organisations become more digitally connected and data-driven, the CISO’s responsibilities have expanded far beyond traditional security measures. Today’s CISO must not only defend against cyber threats but also enable the business to innovate securely, manage complex regulatory environments, and instill a culture of trust across the organisation. This event will explore the evolving role of the CISO as a strategic leader who balances security with business enablement. As digital transformation accelerates, how can CISOs align their security strategies with organisational goals, ensure compliance, and lead their teams in the fight against increasingly sophisticated threats? Key Discussion Points: From Gatekeeper to Strategic Partner: How CISOs can shift from being seen as barriers to innovation to becoming key enablers of business agility and transformation through security. Balancing Risk and Innovation: Learn how top CISOs navigate the delicate balance between mitigating risk and supporting the organisation’s need to innovate and scale in a secure environment. Governance, Risk, and Compliance (GRC): Explore how CISOs are managing an increasingly complex regulatory landscape, ensuring compliance while still driving business objectives forward. Building a Security-First Culture: Practical strategies for CISOs to foster a culture where security is embedded into every part of the business, from boardroom discussions to frontline operations. CISO as Crisis Manager: How to prepare for and lead your organisation through major cybersecurity incidents. From ransomware attacks to data breaches, we’ll discuss how today’s CISO is as much a crisis manager as they are a strategist. Why You Should Attend: As a CISO, your role is evolving faster than ever before. This event is designed to provide you with actionable insights into how to embrace your expanded responsibilities while keeping your organisation safe and secure. Whether you’re focused on aligning security with business goals, navigating regulatory challenges, or leading in times of crisis, this event will equip you with the strategies to lead the next era of cybersecurity.

Business Process Driven Architecture ; Designing systems that follow how your organisation actually works

Too often, architecture is drawn top-down, neat boxes, elegant flows, and little connection to the way teams really work. But what if we flipped it? What if our systems evolved from the actual processes, pains, and needs that drive the business? If you’re tired of systems that look good on slides but frustrate in practice, this session will ground the conversation where value is created, at the process level.

Airbnb Optimizes Usage and Costs by Using Savings Plans and Actionable Cost Data on AWS

To help it achieve its goals, Airbnb looked to Amazon Web Services (AWS), its cloud provider, for data and infrastructure solutions. Using support from AWS and multiple AWS services, Airbnb developed strategies to manage capacity, optimize storage and compute capacity, and build a custom cost and usage data tool. The solutions help Airbnb reduce costs, deliver actionable business metrics, and pursue data-informed efficiency projects across its teams.

Opportunity | Architecting Cost Efficiency to Grow Sustainably

Airbnb’s journey to facilitating connection and community through travel began in 2007 when its first two hosts—and founders—welcomed three guests to their San Francisco home. Since then, the company’s hosts have welcomed over one billion total guest arrivals, with listings across more than 220 countries and regions.

From its early days as a company, Airbnb has powered its business using cloud services from AWS—a strategy that supports its rapidly expanding workloads as well as its need for agile compute and storage solutions. The company decided to invest in transforming its data and usage strategy on AWS. Because Airbnb operations involve hundreds of services and an agile technical culture, the company needed a strategic, centralized, and relatively frictionless approach to leaner purchasing.

Early in Airbnb’s journey, the company used a cost allocation visualization engine, AWS Cost Explorer, which has an easy-to-use interface that helps customers visualize, understand, and manage their AWS costs and usage over time. Later, to make use of its internal data infrastructure and extend the cost visualization capabilities of its data warehousing stack, Airbnb took advantage of data from the AWS Cost & Usage Report, which contains a comprehensive set of AWS cost and usage data and is available at an hourly, daily, or monthly level of granularity, as well as at the management or member account level.

"Using Savings Plans has been a significant improvement to Airbnb’s cloud management process. It’s helped reduce our operational workload while also driving meaningful cost savings for our business.”

Ari Siegel
Senior Finance Manager, Airbnb

Solution | Driving Cost Efficiency Using Insights and Pricing Solutions

Relying on its data warehouse, Airbnb uses the AWS Cost & Usage Report to run a custom pipeline that produces a dynamic view of Airbnb’s cost data and facilitates analytics. Airbnb’s pipeline ingests cost and usage files from Amazon Simple Storage Service (Amazon S3), which offers industry-leading scalability, data availability, security, and performance. To process files, Airbnb uses Amazon EMR, a cloud big data environment for processing vast amounts of data using open-source tools, making it possible for developers to run big data applications and petabyte-scale data analytics faster. Airbnb uses its pipeline to discount and amortize the data and then further customize it to support analytics and produce actionable insights and metrics.

To save on its use of Amazon Elastic Compute Cloud (Amazon EC2), which provides secure, resizable compute capacity in the cloud, Airbnb became an early adopter of Savings Plans, a flexible pricing model offering lower prices compared to Amazon EC2 On-Demand Instances in exchange for a specific usage commitment. Airbnb migrated its Amazon EC2 Reserved Instances to Savings Plans and discontinued its On-Demand Instance usage, resulting in cost savings. “Using Savings Plans has been a significant improvement to Airbnb’s cloud management process. It’s helped reduce our operational workload while also driving meaningful cost savings for our business,” says Ari Siegel, senior finance manager at Airbnb.

Airbnb also manages and saves on storage costs using Amazon S3 Intelligent-Tiering (S3 Intelligent-Tiering), a cloud storage class that delivers automatic cost savings by moving objects between four access tiers when access patterns change. By using S3 Intelligent-Tiering to manage storage locations for objects used by Airbnb’s data warehouse, Airbnb reduced storage costs by approximately 27 percent. Additionally, for replicated data stored for backup, the company uses Amazon S3 Glacier storage classes—a range of storage classes that users can choose from based on the data access, resiliency, and cost requirements of their workloads. Airbnb relies on the AWS Cost & Usage Report for hourly insights into data storage spending on Amazon S3.

Airbnb also manages costs within its logging infrastructure using Amazon OpenSearch Service, which makes it easy to perform interactive log analytics, near-real-time application monitoring, website searches, and more. To help lower costs, Airbnb employed UltraWarm storage for Amazon OpenSearch Service, which provides a cost-effective way to store large amounts of read-only data on Amazon OpenSearch Service. The solution contributed to a 60 percent reduction in Airbnb’s Amazon OpenSearch Service costs.

Outcome | Maturing Operations and Empowering Teams

Airbnb’s finance and technology teams employed a broad range of AWS resources to build cloud efficiency and optimize operations. To work toward data-driven purchasing, the teams also expanded their consultation and engagement using AWS. And by delivering process and visibility improvements, the company helped empower individuals and teams to adopt cost management goals.
