Modelos de Serviço
• Hospedagem – servidores compartilhados
• Colocation e servidores dedicados
• Cloud –Infraestrutura como Serviço
• PaaS – Plataforma como Serviço
Modelos de Serviço • Single tenant / Physical Server
• Single tenant / VM
• Multiple tenants / VM
• Multiple tenants / Physical Server
• Multiple VMs / Physical Server
• Multiple tenants on a pool of virtual/physical servers
IaaS - NIST definition
• “ The capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications.
• The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, and deployed applications; and possibly limited control of select networking components (e.g., host firewalls).”
* http://csrc.nist.gov/publications/nistpubs/800-145/SP800-145.pdf
IaaS - Wikipedia
• “In this most basic cloud service model, cloud providers offer computers, as physical or more often as virtual machines, and other resources. The virtual machines are run as guests by a hypervisor, such as Xen or KVM. Management of pools of hypervisors by the cloud operational support system leads to the ability to scale to support a large number of virtual machines. Other resources in IaaS clouds include images in a virtual machine image library, raw (block) and file-based storage, firewalls, load balancers, IP addresses, virtual local area networks (VLANs), and software bundles.[46] IaaS cloud providers supply these resources on demand from their large pools installed in data centers. For wide area connectivity, the Internet can be used or—in carrier clouds -- dedicated virtual private networks can be configured.”

IaaS - tl;dr
• “Automate infrastructure such as the customer will not know the underlying details, will not manage them and can provision services automagically.”
Cloud - building blocks
• Compute - virtual servers, images • Storage • Network devices: firewall, switches, load
balancer, DNS • Services (management, security, project)
Cloud - Resumido • Hypervisor + servidores + storages + rede = time
sharing/heavy lifting
• Capacity planning diferente de servidores fisicos
• Configuração flexível
• Provisionamento rápido
• Vertical Scaling
• Horizontal scaling
• Serviços de gerenciamento
