From my point of view: Expanding IT Infrastructure on a Budget - Cloud strategies (hybrid and pay-as-you-go) to avoid upfront costs - Virtualization to maximize use of existing resources - Automation to streamline operations and reduce manual labor - Scalable systems (like containers) for cost-effective scaling - Storage optimization to manage data costs efficiently - Open-source software as a budget-friendly alternative - Energy efficiency to lower long-term operational costs - Flexible, modular planning for scalable, future growth These strategies make it possible to expand IT infrastructure affordably while boosting performance and scalability.

Expanding IT infrastructure on a budget means balancing performance with smart resource use. Start by optimizing the resources you already have with tools like Kubernetes and especially using community editions of open-source tools like rancher (for kubernetes), grafana (for observability), metabase (for data), gitlab (for source control and devops), rocketchat or nextcloud (for collaboration) No reason to spend a dime on the software and you can get a much better deal on support then the vendors with services like (shameless plug) hossted

To improve IT efficiency while staying within a budget: 1.Virtualization: Use virtual machines to lower hardware expenses. 2.Cloud Services: Shift tasks to the cloud for easier scaling. 3.Monitoring Tools: Use tools like Nagios to keep track of usage and avoid unnecessary spending. 4.Load Balancing: Spread out traffic evenly to prevent system overloads. 5.Data Compression: Compress and remove duplicate data to save storage space. 6. Open-source Software: Use free tools like Linux and MySQL. 7.Energy Efficiency: Use energy-saving hardware and improve cooling systems. 8.Vendor Negotiation: Review contracts and reduce unnecessary costs. These actions help improve performance without spending too much.

Recomendo utilizar cloud com auto scalling e load balance, pois sua infra cresce conforme a demanda e não precisa ter custo sem utilidade.

Acredito que um estudo baseado no monitoramento / observabilidade dos atuais consumos dos recursos e serviços é um ótimo ponto de partida. Em posse deste estudo, precisamos revisar se as capacidades atuais estão acima do provisionado. Se sim, providenciar o redimensionamento, ou novo provisionamento, que seja mais aderente possível as capacidades necessárias atuais e de breve futuro. Entendo que estes pontos podem ajudar a evitar gastos desnecessários, indisponibilidades, operando com uma infraestrutura dentro das devidas necessidades e capacidades necessárias ao negocio.

First of all...how big is the bank? Use list prices for budget line items & negotiate discounts. To optimize system performance during IT infrastructure expansion on a tight budget, prioritize scalable cloud solutions & virtualization to maximize resource efficiency while minimizing hardware costs. Use performance monitoring to identify & address bottlenecks in real-time, allowing for targeted improvements without a full system overhaul. Leveraging containerization reduces server loads & increases flexibility, while phased upgrades allow you to incrementally enhance capacity as needed. Employing automation tools to streamline processes can further boost performance, reducing the manual workload & maximizing value within budget constraints.
