Golang Warsaw #56 Jakub Wołynko ## Secure access to EC2 (for developers) ## Agenda – introduction – EC2 in native environment – 3-tier architecture intro – alternative methods of resource connection: 9156349143e662/p4_3.jpg) ## 3 -tier architecture - props and cons – full control over resource access – possibilities of disconnection resources from the internet – in general, more secure ## unfortunately – architecture getting more complex – additional costs like VPN, NatGateway – regular resource access become more annoying ## solution one - bastion host ![Image](/uploads/documents/3/6/1/0/361061

## Overview Casdoor is a UI-first Identity Access Management (IAM) / Single-Sign-On (SSO) platform based on OAuth 2.0, OIDC, SAML, and CAS. You need to enable JavaScript to run this app. Casdoor serves Casdoor supports authorization management based on Casbin. It supports ACL, RBAC, ABAC, and RESTful access control models. 4. Casdoor provides phone verification code, email verification code, and password The Application will prompt the user: "Hey, I need some resources and I need your permission to access these resources. Can you go to this URL and enter your username and password for me?" With the

vectorized code ## The talk: ■ share experience with vectorization using std::�md ■ introduce the SIMD_ACCESS library Nowadays, all your CPUs can compute four times faster $$ \begin{aligned}&\begin{vm store operations auto result = simd_load(x, i) + simd_load(y, i) simd_store(z, i, result); Explicit access provided by std::simd ■ Requires rearranging and rewriting the loop body ☑ Different scalar version is the second argument ■ Possible workaround: macro $ \text{SIMD\_ACCESS}(z, i) = \text{SIMD\_ACCESS}(x, i) + \text{SIMD\_ACCESS}(y, i); $ ■ Rewrite (but no rearrangement) necessary ■ Same code

transactions. Think of this as a network overlay. Thus, only those nodes that participate in a channel have access to the smart contract (chaincode) and data transacted, preserving the privacy and confidentiality and endorsement policies, to simplify client applications. • Access control [https://hyperledger-fabric.readthedocs.io/en/release- 1.2/access_control.html: How to configure which client identities can interact functions (transacting, querying, etc) — a blockchain network uses smart contracts to provide controlled access to the ledger.
